Interstate 80 Business (I-80 Bus) is an unofficial business loopofInterstate 80 (I-80) that is 2.26 miles (3.64 km) long and serves as the main street for the US cities of West Wendover, Nevada, and Wendover, Utah, along a roadway named Wendover Boulevard. Wendover Boulevard was originally part of US Route 40 (US 40), which connected CaliforniatoNew Jersey via Nevada and Utah. A portion of the Nevada segment is concurrent with US 93 Alternate (US 93 Alt), and the entire portion in Utah is coterminous with Utah State Route 58 (SR-58). The Nevada Department of Transportation (NDOT) applied for the business loop designation in the early 1980s, but the designation has never been approved; nevertheless, signs are posted in both states. Between July 1976 and 1993, I-80 Bus was concurrent with Nevada State Route 224 (SR 224) in Nevada. (Full article...)

U.S. Route 113 (US 113) is a U.S. Highway that is a spurofUS 13 in the U.S. states of Maryland and Delaware. The route runs 74.75 miles (120.30 km) from US 13 in Pocomoke City, Maryland, north to Delaware Route 1 (DE 1) in Milford, Delaware. In conjunction with DE 1, US 113 is one of two major north–south highways on the Delmarva Peninsula (with US 13) that connect Dover with Pocomoke City and the Eastern Shore of Virginia. The U.S. Highway is the primary north–south highway in Worcester County, Maryland, where it connects Pocomoke City with Snow Hill and Berlin. US 113 is one of three major north–south highways in Sussex County, Delaware, where it connects Selbyville, Millsboro, and Georgetown with Milford. While US 113 does not pass through Ocean City or the Delaware Beaches, the U.S. Highway intersects several highways that serve the Atlantic seaboard resorts, including US 50, Maryland Route 90 (MD 90), US 9, DE 404, DE 16, and DE 1. US 113 is a four-lane divided highway for its whole length.

US 113 follows the corridor of a post road established in the late 18th century to connect the aforementioned towns on the Delmarva Peninsula with Wilmington and Philadelphia. The highway was improved as an all-weather road in the 1910s. In Maryland, the post road was designated one of the original state roads established by the Maryland State Roads Commission (MDSRC) in 1909. In Delaware, the highway was the Selbyville–Dover portion of the DuPont Highway, a roadway whose construction was a grand philanthropic measure of Thomas Coleman DuPont. The DuPont Highway, which was started by DuPont's company and finished by the Delaware State Highway Department (DSHD), spurred economic growth in the tourism and agriculture sectors in southern Delaware. The economic growth resulted in heavy traffic; US 113 was widened in both states in the early 1930s and again in the late 1940s. Bypasses of Dover and Pocomoke City were built in the mid-1930s; the bypassed section of highway in Dover became US 113 Alternate. (Full article...)

State Route 78 (SR 78) is a state highway in the U.S. state of California that runs from Oceanside east to Blythe, traversing nearly the entire width of the state. Its western terminus is at Interstate 5 (I-5) in San Diego County and its eastern terminus is at I-10inRiverside County. The route is a freeway through the heavily populated cities of northern San Diego County and a two-lane highway running through the Cuyamaca MountainstoJulian. In Imperial County, SR 78 travels through the desert near the Salton Sea and passes through the city of Brawley and the Algodones Dunes before turning north on the way to its terminus in Blythe.

SR 78 was one of the original state highways designated in 1934, although portions of the route existed as early as 1900. However, it was not designated east of Brawley until 1959. The freeway section in the North CountyofSan Diego that connects Oceanside and Escondido was built in the middle of the twentieth century in several stages, including a transitory stage known as the Vista Way Freeway, and has been altered several times. An expressway bypass of the city of Brawley was completed in 2012. There are many projects slated to add capacity to the freeway due to increasing congestion in the region. (Full article...)

M-28 is an east–west state trunkline highway that traverses nearly all of the Upper Peninsula of the U.S. state of Michigan, from Wakefield to near Sault Ste. MarieinBruce Township. Along with US Highway 2 (US 2), M-28 forms a pair of primary highways linking the Upper Peninsula from end to end, providing a major access route for traffic from Michigan and Canada along the southern shore of Lake Superior. M-28 is the longest state trunkline in Michigan numbered with the "M-" prefix at 290.373 miles (467.310 km). The entire highway is listed on the National Highway System, while three sections of M-28 are part of the Lake Superior Circle Tour. M-28 also carries two memorial highway designations along its route.

Throughout its course across the Upper Peninsula, M-28 passes through forested woodlands, bog swamps, urbanized areas, and along the Lake Superior shoreline. Sections of roadway cross the Ottawa National Forest and both units of the Hiawatha National Forest. Some of the other landmarks accessible from M-28 include the Seney Stretch, Seney National Wildlife Refuge and several historic bridges. (Full article...)

State Route 67 (SR 67) is a state highwayinSan Diego County, California, United States. It begins at Interstate 8 (I-8) in El Cajon and continues to Lakeside as the San Vicente Freeway before becoming an undivided highway through the eastern part of Poway. In the town of Ramona, the route turns into Main Street before ending at SR 78. SR 67 provides direct access from the city of San Diego to the East County region of San Diego County, including Ramona and Julian.

The route has existed as a railroad corridor since the turn of the 20th century. A highway known as the Julian road was built by 1913, and was designated as Legislative Route 198 in the state highway system by 1935. Route 198 was renumbered SR 67 in the 1964 state highway renumbering. A freeway south of Lakeside was built in the late 1960s, and opened to traffic in 1970. Since then, the portion of the highway north of Lakeside has become known for a high number of traffic accidents and related fatalities. The California Department of Transportation (Caltrans) has made several attempts to remedy the problem and make the road safer. (Full article...)

New York State Route 28N (NY 28N) is an east–west state highway in the North CountryofNew York in the United States. It extends for 50.95 miles (82.00 km) through the Adirondack Mountains from Blue Mountain LaketoNorth Creek. The route is a northerly alternate route to NY 28 between both locations; as such, it passes through several communities that NY 28 bypasses to the south. The westernmost 10 miles (16 km) of NY 28N overlap with NY 30 through the town of Long Lake. NY 28N and NY 30 split in the hamlet of Long Lake, from where NY 30 heads to the north and NY 28N proceeds eastward through mountainous regions of Adirondack Park.

The 40-mile (64 km) section of NY 28N not concurrent with NY 30 is designated as the Roosevelt–Marcy Trail, a scenic byway named for Theodore Roosevelt, who was then the Vice President of the United States. The byway marks the path Roosevelt took in 1901 to reach North Creek from Mount Marcy after learning that President William McKinley had been assassinated. The route has a rather scant history before its designations. The road originated as an old highway stretching from Warren County to Long Lake. It was used for transportation in the iron ore industry in Newcomb, and for the lumber industry in Minerva. New York State gained control of the road in 1909. The NY 28N designation was assigned as part of the 1930 renumbering of state highways in New York, incorporating part of pre-1930 NY 10. (Full article...)

State Route 128 (SR-128) is a 44.564-mile-long (71.719 km) state highway in the U.S. state of Utah. The entire length of the highway has been designated the Upper Colorado River Scenic Byway, as part of the Utah Scenic Byways program. This road also forms part of the Dinosaur Diamond Prehistoric Highway, a National Scenic Byway. Residents of Moab frequently refer to SR-128 as "the river road", after the Colorado River, which the highway follows.

The highway was originally constructed to connect rural cities in eastern Utah with Grand Junction, Colorado, the largest city in the region. Part of the highway was merged into the Utah state highway system in 1931; the rest was taken over by the state and assigned route number 128 in 1933. Today, the highway is used as a scenic drive for visitors to the area. (Full article...)

US Highway 31 (US 31) is a part of the United States Numbered Highway System that runs from Alabama to the Lower Peninsula of the US state of Michigan. In Michigan, it is a state trunkline highway that runs from the Indiana–Michigan state line at Bertrand Township north to its terminus at Interstate 75 (I-75) south of Mackinaw City. Along its 355.2-mile-long (571.6 km) route, US 31 follows the Michigan section of the St. Joseph Valley Parkway as well as other freeways and divided highways northward to Ludington. North of there, the trunkline is a rural undivided highway through the Northern Michigan tourist destinations of Traverse City and Petoskey before terminating south of Mackinaw City. Along its route, US 31 has been dedicated in memory of a few different organizations, and sections of it carry the Lake Michigan Circle Tour (LMCT) moniker. Four bridges used by the highway have been recognized for their historic character as well.

The first highways along the route of the modern US 31 corridor were the West Michigan Pike, an auto trail from 1913, and later a pair of state trunklines (the original M-11 and M-58) in 1919. These state highways were redesignated US 31 on November 11, 1926, when the US Highway System was approved. Since then, the highway has been realigned in places. The highway crossed the Straits of Mackinac by ferry for about a decade in the 1920s and 1930s before the Mackinac Bridge was built, connecting to US 2 north of St. Ignace. Later, sections were converted into freeways starting in the 1950s. These segments opened through the subsequent decades with the last one opening in 2022. Future plans by the Michigan Department of Transportation (MDOT) include a bypass of Grand Haven. (Full article...)

State Route 56 (SR 56) is an east–west state highway in the U.S. state of California. It runs 9.210 miles (14.822 km) from Interstate 5 (I-5) in the Carmel Valley neighborhood of San DiegotoI-15. The eastern terminus of the highway is also the western end of the Ted Williams Parkway. SR 56 serves as an important connector between I-5 and I-15, being the only east–west freeway between SR 78innorth San Diego County, several miles away, and SR 52 near Marine Corps Air Station Miramar. It is also named the Ted Williams Freeway, after the San Diego-born baseball player.

SR 56 was added to the state highway system in 1959 as Legislative Route 278, and was renumbered SR 56 in the 1964 state highway renumbering. Plans in 1964 were to connect SR 56 to the north end of SR 125 and continue east to SR 67, but these plans did not come to fruition. The eastern end from Black Mountain Road to I-15 was completed in 1993; the western end from I-5 to Carmel Creek Road was completed in 1995 after several lawsuits filed by the Sierra Club and other community groups. The two ends were not connected until the middle portion of the freeway was completed in 2004. The delay was largely due to funding issues and environmental concerns. (Full article...)

M-35 is a state trunkline highway in the Upper Peninsula (UP) of the US state of Michigan. It runs for 128 miles (206 km) in a general north–south direction and connects the cities of Menominee, Escanaba, and Negaunee. The southern section of M-35 in Menominee and Delta counties carries two additional designations; M-35 forms a segment of the Lake Michigan Circle Tour, and it is the UP Hidden Coast Recreational Heritage Trail, which is a part of what is now called the Pure Michigan Byways Program. Along the southern section, the highway is the closest trunkline to the Green Bay, a section of Lake Michigan. The northern section of the highway turns inland through sylvan areas of the UP, connecting rural portions of Delta and Marquette counties.

M-35 is an original state trunkline that was first signposted in 1919, that was intended to run from Menominee in the south to near Big Bay in the north, before it was to turn toward L'Anse to end at Ontonagon. However, the section through the Huron Mountains in northern Marquette and Baraga counties was never built. Automobile pioneer Henry Ford helped halt this construction to gain favor with and membership into the exclusive Huron Mountain Club. Some discontinuous sections were later ceded to local control. The northern segment of the route between Ontonagon and Baraga was retained as a discontinuous segment of the highway; this northern segment was later redesignated as another state trunkline. The northern end was later rerouted out of the City of Negaunee into Negaunee Township to avoid mining activity near Palmer. (Full article...)

U.S. Highway 30 (US 30) is a major east–west U.S. Highway which spans 330 miles (530 km) across the state of Iowa. It is the longest primary highway in the state and is maintained by the Iowa Department of Transportation (Iowa DOT). The route in Iowa begins at the Missouri River crossing at Blair, Nebraska, and ends at the Mississippi River crossing at Clinton, Iowa. Along the way, it serves Denison and Carroll in western Iowa, Boone, Ames, and Marshalltown in central Iowa, and Tama, Cedar Rapids, and DeWitt in eastern Iowa. Cutting across the central portion of the state, US 30 runs within close proximity of the Union Pacific Railroad's Overland Route for its entire length.

US 30 was conceived as a part of the Lincoln Highway, the first transcontinental highway in the United States. A route through Iowa was chosen because of the important link between Omaha, Nebraska, and Chicago, Illinois. As the U.S. Highway System came into being in the 1920s, and the Lincoln Highway became US 30, federal money started to pay for paving Iowa's dirt roads. By 1931, the route had been paved across the entire state. (Full article...)

New York State Route 175 (NY 175) is an east–west state highway located entirely within Onondaga County, New York, in the United States. The 15.46-mile (24.88 km) route begins at an intersection with U.S. Route 20 (US 20) east of the village of Skaneateles and passes through the village of Marcellus before ending at a junction with US 11inSyracuse. The highway was designated in the 1930 renumbering of state highways in New York.

The section of NY 175 from the town of Marcellus to the end of the NY 173 concurrency is part of the Seneca Turnpike, which was established in 1800 and dissolved in 1852. This portion of the Seneca Turnpike was instrumental in the development of the villages of Skaneateles and Marcellus. When designated in 1930, NY 175 was on a rural stretch of highway connecting Marcellus to Onondaga, and brought about an increase in population and development along its route. (Full article...)

Interstate 69 (I-69) is a part of the Interstate Highway System that will eventually run from the Mexican borderinTexas to the Canadian borderatPort Huron, Michigan. In Michigan, it is a state trunkline highway that enters the state south of Coldwater and passes the cities of Lansing and Flint in the Lower Peninsula. A north–south freeway from the Indiana–Michigan border to the Lansing area, it changes direction to east–west after running concurrently with I-96. The freeway continues to Port Huron before terminating in the middle of the twin-span Blue Water Bridge while running concurrently with I-94 at the border. There are four related business loops for I-69 in the state, connecting the freeway to adjacent cities.

Predecessors to I-69 include the first M-29, US Highway 27 (US 27), M-78 and M-21. The freeway was not included on the original Interstate Highway System planning maps in the mid-1950s, but it was added in 1958 along a shorter route. Michigan built segments of freeway for the future Interstate in the 1960s, and the state was granted additional Interstate mileage in 1968 to extend I-69 north and east to Flint. Later extensions in 1973 and 1987 resulted in the modern-day highway. The first freeway segment designated as I-69 in Michigan opened in 1967, and the last was completed in 1992, finishing Michigan's Interstate System. US 27 previously ran concurrently with I-69 from the Indiana–Michigan state line north to the Lansing area, but this designation was removed in 2002. (Full article...)

Interstate 196 (I-196) is an auxiliary Interstate Highway that runs for 80.6 miles (129.7 km) in the US state of Michigan. It is a state trunkline highway that links Benton Harbor, South Haven, Holland, and Grand Rapids. In Kent, Ottawa, and Allegan counties, I-196 is known as the Gerald R. Ford Freeway, or simply the Ford Freeway, after President Gerald Ford, who was raised in Grand Rapids and served Michigan in the House of Representatives for 25 years. This name generally refers only to the section between Holland and Grand Rapids. I-196 changes direction; it is signed as a north–south highway from its southern terminus to the junction with US Highway 31 (US 31) just south of Holland, and as an east–west trunkline from this point to its eastern terminus at an interchange with I-96, its parent highway. There are three business routes related to the main freeway. There are two business loops (BL I-196) and one business spur (BS I-196) that serve South Haven, Holland and the Grand Rapids areas. Another business spur for Muskegon had been designated relative to the I-196 number.

The freeway numbered I-196 is the second in the state to bear the number. Originally to be numbered as part of the I-94 corridor in the state, the Benton Harbor–Grand Rapids freeway was given the I-96 number in the 1950s while another Interstate between Muskegon and Grand Rapids was numbered I-196. That I-196 was built in the late 1950s and completed in the early 1960s. The first segment of the current I-196 was opened as I-96 near Benton Harbor in 1962. Michigan officials requested a change in 1963 which reversed the two numbers, and the subsequent segments of freeway opened northward to Holland and from Grand Rapids westward under the current number. The gap between Holland and Grandville was filled in the 1970s, and a section of freeway that runs through downtown Grand Rapids was rebuilt as a wider freeway in 2010. (Full article...)

U.S. Route 117 (US 117) is a north–south United States Highway located completely within the stateofNorth Carolina. A spur route of US 17, the highway runs for 114 miles (183 km) from the Port of Wilmington, south of downtown Wilmington, to US 301 near Wilson. From its southern terminus, US 117 runs along Shipyard Boulevard and College Road, concurrent with North Carolina Highway 132 (NC 132) through Wilmington. US 117 intersects the eastern terminus of Interstate 40 (I-40) and parallels the interstate until reaching Faison, passing through Burgaw, Wallace, and Warsaw. The highway diverges from I-40 in Faison, running north-northeast through Mount Olive, Goldsboro, and Pikeville to its northern terminus. US 117 meets the southern end of I-795inGoldsboro, and parallels that route before reaching its northern terminus at US 301 south of Wilson.

The general alignment of US 117 was originally signed as NC 40, one of the original North Carolina State Highways running from Fort Fisher to the Virginia state line. Upon the creation of the United States Numbered Highway System in 1926, US 17-1 was assigned concurrent with NC 40 from Wilmington to Virginia. US 17-1 was decommissioned in 1932 and US 117 was established, running from Conway, South Carolina to Wilson via Myrtle Beach and Wilmington. In 1939, US 17 replaced US 117 between Conway and Wilmington, truncating the southern terminus to Downtown Wilmington. US 117 has undergone several realignments since 1940, some of which have created special routes of US 117. In 2003, the southern terminus of US 117 was adjusted again, rerouting the highway along College Road and Shipyard Boulevard to the Port of Wilmington. Between 2006 and 2007, US 117 was routed onto a new freeway between Goldsboro and US 264 in Wilson. The freeway was subsequently renumbered as I-795 and US 117 was placed on its original routing north of Goldsboro. A southerly extension of I-795 from Goldsboro to I-40 is planned along the US 117 corridor. (Full article...)

Route 13 is a short state highway in the communities of Point Pleasant and Bay Head, New Jersey, both of which are in Ocean County. The route consists of the Lovelandtown Bridge, a vertical-lift bridge over the Point Pleasant Canal, and a part of Bridge Avenue, which is mostly maintained by the county as County Route 632 (CR 632). The route was unsigned until new mileposts were installed in 2017. Route 13 was designated in the 1953 New Jersey state highway renumbering as a re-designation of Route 13E from Hollywood Boulevard to Bay Avenue.

The route was first assigned in 1938, when the state took over maintenance of the fifth segment of Ocean County Route 13 built in 1929, intending it to reach old Route 37 (now part of Route 35) in Bay Head from Beaver Dam Road, a distance of 1.76 miles (2.83 km). The takeover did not reach that point, and the bridge and its approaches count for 0.56 miles (0.90 km) of the intended length. The original bridge collapsed in 1962, and a temporary structure was erected later that year. Planning for a permanent replacement bridge continued for several years until construction finally began in 1970. This structure opened in 1972, but closed immediately afterward due to a failure of the lift mechanism, which was fixed by the end of the year. In late 2004, the bridge and its approaches received a rehabilitation. (Full article...)

M-142 is an east–west state trunkline highwayinThe Thumb region of the US state of Michigan. It is a "trans-peninsular" highway in that it travels through an agricultural area from Bay PortonSaginaw BaytoHarbor BeachonLake Huron. The current trunkline in Huron County was originally parts of other state highways that date back to the initial 1919 signposting of the state highway system in the state. The designation was applied in 1939, and the road has remained unchanged since it was completely paved in the 1950s. One other highway, near Lake City, carried the number in the 1930s.

Mississippi Highway 531 (MS 531) is a state highway in central Mississippi. The road starts at MS 28 near Taylorsville and travels northeastward. It crosses from Smith CountytoJasper County, and ends at MS 18 in the town of Bay Springs. The route was designated in 1956 along its current alignment, and it was paved by 1960. (Full article...)

Interstate 140 (I-140) and North Carolina Highway 140 (NC 140) is a 25.4-mile (40.9 km) auxiliary Interstate Highway and state highway in the U.S. stateofNorth Carolina. Officially designated the John Jay Burney Jr. Freeway, it serves as a bypass of Wilmington. The western terminus of the highway is at U.S. Route 17 (US 17) near Winnabow. It heads north in western Leland before turning to the east north of an interchange with U.S. Route 74 (US 74)/U.S. Route 76 (US 76). I-140 crosses the Cape Fear River north of Navassa and the Northeast Cape Fear River northwest of Wrightsboro. I-140 ends at Interstate 40 (I-40), and the route number changes to NC 140. NC 140 continues to the east, ending at US 17 in Kirkland.

The need for a bypass north of Wilmington was identified by the North Carolina Department of Transportation (NCDOT) in 1972. However, the first contract for construction was not awarded until 2000. In August 2005, the first segment of I-140 between I-40 and North Carolina Highway 133 (NC 133) opened. This was followed by a westward extension to U.S. Route 421 (US 421) and an eastward extension to US 17 in June 2006. US 17 was routed along the entirety of the freeway between Kirkland and US 421, running concurrently with I-140. Construction on the western segment between Winnabow and US 74/US 76 began in March 2010 and was opened in September 2014. This segment was temporarily designated as NC 140 as it lacked connection with I-140 to the east. The final segment between US 74/US 76 and US 421 began construction in 2014 and was completed in 2017. I-140 was routed along the entirety of the freeway west of I-40. Additionally, US 17 was removed from its concurrency with I-140, being rerouted through Wilmington in 2017. The remaining section between I-40 and Kirkland was subsequently renumbered as NC 140.

State Route 100 (SR 100) is a 4.68-mile-long (7.53 km) state highway in the U.S. stateofWashington, serving Cape Disappointment State ParkinPacific County. The highway travels counterclockwise from U.S. Route 101 (US 101) in Ilwaco south to Cape Disappointment and north to an intersection with itself in Ilwaco. SR 100, part of the Lewis and Clark Trail Scenic Byway, serves as a loop route and has a spur route that serves the state park and a Coast Guard station. SR 100 was established in 1991 on the existing North Head Road, which was a paved county road by the late 1950s. The highway was washed away during a 1994 winter storm and had its spur route shortened in 2006. (Full article...)

Highway 142 (AR 142) is a north–south state highwayinChicot County, Arkansas. The route starts its southern terminus at Levee Road near Lakeport. The road then travels north, passing through the Lakeport Plantation. It ends at its northern terminus at U.S. Route 82 (US 82) and US 278inShives. AR 142 was designated in 1931, from US 61 to the Mississippi River, and part of the route was redesignated as part of US 82 in 1940. The route was paved in asphalt by 1962. The route is maintained by the Arkansas Department of Transportation (ArDOT). (Full article...)

In Oklahoma, U.S. Highway 62 (US 62) runs diagonally across the state, from the Texas state line in far southwestern Oklahoma to the Arkansas state line near Fayetteville. US-62 spends a total of 402.48 miles (647.73 km) in the Sooner State. The highway passes through fifteen of Oklahoma's counties. Along the way the route serves two of Oklahoma's largest cities, Lawton and Oklahoma City, as well as many regionally important cities, like Altus, Chickasha, Muskogee, and Tahlequah. Despite this, US-62 has no lettered spur routes like many other U.S. routes in Oklahoma do.

Since 1930, US-62 has been a part of Oklahoma's highway system. The section of the Interstate system's route that passes through Oklahoma City was altered several times after it was established in order to accommodate the presence of the new freeways. The present-day route of US-62 includes concurrencies with I-44, I-240, I-35, and I-40. (Full article...)

New York State Route 37 (NY 37) is a state highway in the North CountryofNew York in the United States, extending for 127.40 miles (205.03 km) on a west–east axis. The western terminus of the route is at an intersection with U.S. Route 11 (US 11) in Pamelia, Jefferson County. Its eastern terminus is at a junction with US 11, NY 11B, and NY 30inMalone, Franklin County. In between the termini, NY 37 passes through Ogdensburg and Massena. It is a two-lane, nondivided, full access roadway for most of its entire length, except for portions between Massena and western Franklin County, where the route widens to a four-lane divided highway.

NY 37 was assigned in 1930 to the portion of the Theodore Roosevelt International Highway between Redwood and Malone as well as to a previously unnumbered roadway between Watertown and Redwood. The Redwood–Malone portion was originally part of NY 3 when the first set of posted routes in New York were assigned in 1924. NY 37 has since been rerouted in areas, primarily near Ogdensburg and Massena. (Full article...)

Delaware Route 37 (DE 37) is a state highway in New Castle County, Delaware. The route runs from DE 273inPleasantville northeast to U.S. Route 202 (US 202) and DE 141 north of the Wilmington Airport near Wilmington Manor. The road runs through suburban neighborhoods and passes along the edge of Wilmington Airport along Airport Road before it provides access to a business park along Commons Boulevard. The Airport Road portion of DE 37 was originally a dirt road that was paved by 1942. DE 37 was assigned to its current alignment by 1985. (Full article...)

Legacy Parkway (designated as State Route 67, SR-67) is an 11.5-mile-long (18.5 km) four-lane controlled-access parkway located almost completely within Davis County in the northern part of the U.S. state of Utah. The parkway travels north from Interstate 215 (I-215) in northwestern Salt Lake City to an interchange named the Wasatch Weave in Farmington with two intermediate interchanges providing access to Woods Cross and Centerville. Wetlands of the nearby Great Salt Lake and nature preserves border the western side of the parkway while the eastern side roughly parallels Union Pacific and Utah Transit Authority rail lines and I-15. On average, between 20,000 and 23,000 vehicles use the parkway daily.

Construction began in 2006 and was completed in 2008, with the parkway opening in September of the same year. The parkway was controversial in its construction and was challenged in court several times before a compromise was met between the state and the Sierra Club, which limited the speed on the road and banned semi-trucks on the highway except in emergencies. In addition to the restrictions on speed and trucks, the road was reduced from a six-lane expressway to a four-lane parkway.

State Road 538 (SR 538), also known as the Poinciana Parkway, is a 7.2-mile (11.6 km) controlled-access toll road built in Osceola and Polk Counties, Florida. Construction began in 2013 and was completed in 2016. The road had been planned for decades to provide a traffic outlet from Poinciana northwest to US 17/US 92 and Interstate 4. Costs skyrocketed after land along the planned route was converted to a mitigation bank, requiring a bridge to span most of the 1.2 miles (1.9 km) stretch through the restored wetland. The road was originally planned to be built by Avatar—the primary developer of Poinciana—as a four-lane, limited-access highway; after the decision was made to build the bridge across the mitigation bank a toll was planned for the bridge segment of the road, but the collapse of the 2000s housing bubble and increased costs forced Avatar to abandon their plans to build the private toll road. About the same time, Osceola County formed the Osceola County Expressway Authority to build a loop road around the Kissimmee-St.Cloud area, which would include the Poinciana Parkway. (Full article...)
