In Amarillo, I-27 is commonly known as the '''Canyon Expressway''' (or '''Canyon E-Way'''), although it is also called '''Canyon Drive''' on its access roads. I-27 was officially designated the '''Marshall Formby Memorial Highway''' after former attorney and State Senator Marshall Formby in 2005.<ref name="HDF-IH-27"/> The entire length of I-27 replaced [[U.S. Route 87 in Texas|US Highway&nbsp;87]] (US&nbsp;87) for through traffic. An extension of I-27 north to [[Raton, New Mexico]], and south to [[Laredo, Texas]], was approved in 2022.

[[File:Interstate 27 southern terminus.jpg|thumb|left|Southern terminus in Lubbock]]
I-27 parallels the [[BNSF Railway]]'s Plainview Subdivision, which splits from its [[Chicago]]–[[Southern California]] Transcon line at [[Canyon, Texas|Canyon]] and runs south to Lubbock. A large amount of the alignment is on former US&nbsp;87, but several portions through built-up areas have been bypassed, as well as two longer areas where US&nbsp;87 still follows the old road.<ref name="Google">{{google maps |url = https://maps.google.com/maps?f=d&hl=en&geocode=2513384705999631135,33.529277,-101.844060&saddr=35.192749,-101.837339&daddr=US-87+N+%4033.529277,+-101.844060&mra=mi&mrsp=0,1&sz=14&sll=35.181525,-101.838284&sspn=0.031709,0.057678&ie=UTF8&ll=34.438628,-101.90918&spn=2.047679,3.691406&z=8 |title = Overview Map of I-27 |access-date = February 15, 2008 }}</ref>

The Interstate begins at a point along the four-lane US&nbsp;87 freeway south of downtown Lubbock. Mile&nbsp;0 is posted near 77th Street,<ref name="Mapbook 433">{{Texas Mapbook|year=2018|page=433|access-date=August 3, 2018}}</ref> about five blocks south of [[Texas State Highway Loop 289|Loop&nbsp;289]]. [[Exit number]]ing begins just to the south, with exit&nbsp;1 at the 82nd Street interchange; the freeway becomes six lanes at its north end. The Loop&nbsp;289 interchange is a [[Cloverleaf interchange|cloverleaf]] between the oneway [[frontage road]]s of each highway, and with direct ramps from I-27 south to Loop&nbsp;289 west (exit&nbsp;1A) and Loop&nbsp;289 east to I-27 north. [[U.S. Route 84 in Texas|US&nbsp;84]] (Avenue Q and Slaton Highway) crosses I-27 at a [[three-level diamond interchange]], with an extra approach from the northeast carrying Avenue A into the junction. Exit&nbsp;1B connects I-27 south to US&nbsp;84 and the Loop&nbsp;289 frontage roads, while all traffic from US&nbsp;87 north to US&nbsp;84, Avenue A, or Loop&nbsp;289 must use exit&nbsp;1 for 82nd Street.<ref name="Google"/>

The six-lane cross section that began at exit&nbsp;1 remains through Lubbock. Major junctions in that city include [[U.S. Route 62 in Texas|US&nbsp;62]]/[[Texas State Highway 114|State Highway&nbsp;114]] (SH&nbsp;11, 19th Street; exit&nbsp;3) and [[U.S. Route 82 in Texas|US&nbsp;82]] (Marsha Sharp Freeway; exit&nbsp;4). Between these two interchanges, the frontage roads temporarily end as I-27 crosses over a rail line. [[Texas State Highway Spur 326|Spur&nbsp;326]] (Avenue Q) merges with I-27 at exit&nbsp;6A, and exit&nbsp;6B is a [[split diamond interchange]] with Loop&nbsp;289. The outer lanes leave at [[Farm to Market Road 2641]] (FM&nbsp;2641, Regis Street; exit&nbsp;8), reducing I-27 to two lanes in each direction as it passes [[Lubbock Preston Smith International Airport]] and leaves the city.<ref name=Google/>

[[File:Downtown Lubbock from I-27 2005-09-10.jpeg|thumb|left|Downtown Lubbock, as seen from I-27]]
I-27 crosses over the Plainview Sub for the first time north of [[Farm to Market Road 1294|FM&nbsp;1294]] (Drew Street, exit&nbsp;11), and another short gap exists in the frontage roads there. North of the overpass, the frontage roads are two-way; I-27 then passes through [[New Deal, Texas|New Deal]], bypassing the central part of the town to the west. Old US&nbsp;87 between exits&nbsp;13 and 15 is now [[Texas State Highway Loop 461|Loop&nbsp;461]]; at exit&nbsp;15, I-27 begins to parallel the rail line, just to its west. Along this part of the highway, and other similar portions, slip ramps still connect the mainlanes with the frontage roads, but intersecting roads pass over all four roadways and the railroad on a long bridge; a pair of two-way roadways connects the frontage roads to the crossroad, with the one on the east crossing the railroad at-grade.<ref name=Google/>

As it approaches [[Abernathy, Texas|Abernathy]], I-27 curves west away from the Plainview Sub. The old main road through the city, between exits&nbsp;20 and 22, is now [[Texas State Highway Loop 369|Loop&nbsp;369]]; I-27 passes through 1.5&nbsp;blocks to the east. Despite I-27's location north of Abernathy, {{Convert|0.5|mi|km}} west of the rail line, all interchanges between Abernathy and [[Hale Center, Texas|Hale Center]], except the one at [[Farm to Market Road 54|FM&nbsp;54]] (exit&nbsp;24), use the same configuration where the intersecting road crosses over all roadways. Approaching Hale Center, I-27 curves northeast as it splits from [[Farm to Market Road 1424|FM&nbsp;1424]] (exit&nbsp;36) at a simple [[diamond interchange]]. The freeway passes through the city one block east of the old road, now [[Interstate 27 Business (Hale Center, Texas)|Business I-27-T]] (Bus. I-27-T), which is accessed at exits&nbsp;36 and 38. As it leaves Hale Center, I-27 turns to the northeast, following the northwest side of the rail line.<ref name=Google/>

The next two interchanges along the railroad between Hale Center and [[Plainview, Texas|Plainview]] use the same style, in which the crossroad goes over everything. [[Interstate 27 Business (Plainview, Texas)|Bus. I-27-U]] splits at exit&nbsp;45, a modified Y interchange, to pass through Plainview, and I-27 travels west of that city on a bypass. The two outer interchanges on this bypass, [[Farm to Market Road 3466|FM&nbsp;3466]] (exit&nbsp;48) and Quincy Street (exit&nbsp;51), are handled in the same way as the interchanges along the railroad, but the other two, [[U.S. Route 70 in Texas|US&nbsp;70]] (exit&nbsp;49) and [[Texas State Highway 194|SH&nbsp;194]] (exit&nbsp;50), are standard diamonds. Between exits&nbsp;49 and 50 is another overpass over the frontage roads—24th Street—with no separate slip ramps. Bus. I-27-U ends at a [[trumpet interchange]] (exit&nbsp;53) north of Plainview, where I-27 again begins to parallel the Plainview Sub to the west. Both interchanges between this one and the first split with US&nbsp;87 (exit&nbsp;61), a modified Y interchange south of [[Kress, Texas|Kress]], continue the pattern with the crossroad bridging over everything.<ref name=Google/>

After it leaves US&nbsp;87, I-27 is no longer next to the rail line, but it continues to handle interchanges as it does alongside the line, except at [[Texas State Highway 86|SH&nbsp;86]] (exit&nbsp;74), a standard diamond interchange that serves [[Tulia, Texas|Tulia]]. US&nbsp;87 rejoins the freeway at a modified diamond interchange (exit&nbsp;77) north of Tulia, at which I-27 crosses to the east side of the Plainview Sub before paralleling it to that side. After several of the typical interchanges adjacent to the railroad, US&nbsp;87 splits again at a modified Y interchange (exit&nbsp;88) south of [[Happy, Texas|Happy]]. Except for the northernmost one, all the interchanges on the bypass of Happy and [[Canyon, Texas|Canyon]] are diamond interchanges; there is a break in the frontage road north of [[Farm to Market Road 3331|FM&nbsp;3331]] (exit&nbsp;108), where I-27 crosses the [[Prairie Dog Town Fork Red River]]. Exits&nbsp;109 (Country Club Road) and 110 (US&nbsp;87 south, [[U.S. Route 60 in Texas|US&nbsp;60]] west) are integrated, with some access to one road provided via the other.<ref name=Google/>

[[File:Interstate 27 northern terminus.jpg|thumb|Northern terminus at I-40 south of downtown Amarillo]]
I-27 is overlapped by US&nbsp;60 and US&nbsp;87 from exit&nbsp;110 north of Canyon to the end of the Interstate in Amarillo; here, the frontage roads are one-way. Several near the south end are handled by bridging the intersecting road over all roadways, but, once I-27 crosses [[Texas State Highway Loop 335|Loop&nbsp;335]] (exit&nbsp;116), almost all interchanges are diamond interchanges. At exit&nbsp;119A, which marks the south end of the six-lane cross section in Amarillo, Hillside Road passes under both the mainlanes and the frontage roads, with two ramps providing partial access. Other connections with Hillside Road are made via Western Street (exit&nbsp;119B), which crosses the frontage roads at grade. The end of I-27 at [[Interstate 40 in Texas|I-40]] (exit&nbsp;123B) is a fully directional [[turbine interchange]]; [[U.S. Route 287 in Texas|US&nbsp;287]] also passes through, using I-40 to the east and US&nbsp;60/US&nbsp;87 to the north. Four lanes continue beyond I-40 and are joined by several from the I-40 ramps, making the northernmost portion of the Canyon Expressway five lanes in each direction. Several blocks beyond I-40, the highway ends at a split into two [[one-way pair]]s. Northbound traffic feeds onto Fillmore Street (US&nbsp;87 north) and Buchanan Street (US&nbsp;60 east and US&nbsp;287 north), while southbound traffic approaches on Taylor Street (US&nbsp;287 south) and Pierce Street (US&nbsp;60 west and US&nbsp;87 south). The rightmost of the five northbound lanes is barrier-separated from the rest, forcing traffic exiting I-40 west onto Buchanan Street. Through the I-40 interchange and the split, the frontage roads are discontinuous.<ref name=Google/>

[[File:Interstate 27 Tulia.JPG|thumb|right|I-27 in Tulia]]
The roadway between Lubbock and Amarillo was part of the Puget Sound to Gulf Highway ([[Texas State Highway 9 (1917–1971)|SH&nbsp;9]]), one of the original state highways defined in 1917.<ref>[[Commerce Journal]], Highway Commission Adopts 25 Highways, July 6, 1917{{full citation needed|date=November 2017}}</ref> In 1926, it became part of [[U.S. Route 385 (1926)|US&nbsp;385]],<ref name="1926 map">{{cite map |author1= [[Bureau of Public Roads]] |author2= [[American Association of State Highway Officials]] |date= November 11, 1926 |title= United States System of Highways Adopted for Uniform Marking by the American Association of State Highway Officials |url= https://commons.wikimedia.org/wiki/File:United_States_System_of_Highways_Adopted_for_Uniform_Marking_by_the_American_Association_of_State_Highway_Officials.jpg |scale= 1:7,000,000 |location= Washington, DC |publisher= [[United States Geological Survey]] |oclc= 32889555 |access-date= November 7, 2013 |via= [[Wikimedia Commons]] |name-list-style= amp |archive-date= April 13, 2017 |archive-url= https://web.archive.org/web/20170413153913/https://commons.wikimedia.org/wiki/File:United_States_System_of_Highways_Adopted_for_Uniform_Marking_by_the_American_Association_of_State_Highway_Officials.jpg |url-status= live }}</ref> which was absorbed into [[U.S. Route 87 in Texas|US&nbsp;87]] in 1935.<ref>{{TxDOT|US|87|link=no}}</ref> The SH&nbsp;9 [[Concurrency (road)|overlap]] was dropped in the 1939&nbsp;renumbering.<ref>[[H.M.

The completion of I-27, costing a total of $453.4&nbsp;million (equivalent to ${{Formatprice|{{inflation|US-GDP|453400000|1992}}}} in {{Inflation/year|index=US-GDP}}{{Inflation/fn|index=US-GDP}}), encouraged growth along the highway: toward the northside of Lubbock and the southwest in Amarillo. Plainview, the largest city between Lubbock and Amarillo, has the only significant [[retail cluster]] outside the two terminal cities and has attracted several industries. On the other hand, Tulia, once a self-contained community with local businesses, was bypassed by I-27, and residents must now drive elsewhere for most shopping needs.<ref name=FHWA/>
