Interstate 95 (I-95) is a part of the Interstate Highway System that runs north–south from Miami, FloridatoHoulton, Maine. The highway enters Maine from the New Hampshire state line in Kittery and runs for 303 miles (488 km) to the Canada–United States border at Houlton. It is the only primary Interstate Highway in Maine. In 2004, the highway's route between Portland and Gardiner was changed so that it encompasses the entire Maine Turnpike (including the former I-495 between Falmouth and Gardiner), a toll road running from Kittery to Augusta. As an Interstate Highway, all of I-95 in Maine is included in the National Highway System, a network of roads important to the country's economy, defense, and mobility.[2]
I-95 enters Maine as a six-lane highway from New Hampshire on the Piscataqua River Bridge, which connects Portsmouth, New Hampshire, with Kittery. At mile 0.38, the highway becomes the Maine Turnpike. The highway runs in a general northeasterly direction, parallel with US Route 1 (US 1), at this point. I-95 bypasses the Biddeford/Saco area, with a spur route, I-195, connecting to Old Orchard Beach.
I-295 splits eastward from I-95 at mile 44 in Scarborough toward Portland Downtown, and Maine's Midcoast region. At this point, I-95 turns inland to the north, bypassing Portland Downtown while providing access to Portland International Jetport. I-95 narrows from six lanes to four lanes at mile 49 near the Portland-Falmouth border. At mile 53 in Falmouth, the highway meets unsigned I-495, also called the Falmouth Spur. Until January 2004, I-95 followed the Falmouth Spur and I-295 between Falmouth and Gardiner.

I-95 continues north along its concurrency with the Maine Turnpike (which was I-495 prior to 2004) through GraytoAuburn and Lewiston, bypassing the latter two cities to the south. The highway then runs in an easterly direction to meet the northern terminus of I-295 at Gardiner. From there, I-95 parallels the Kennebec River past Augusta and Waterville. The highway then crosses the river at Fairfield and then turns northeast along the Sebasticook River past PittsfieldtoNewport.
I-95 then continues east alongside US 2 from Newport to Bangor, where I-395 connects to the city of Brewer. The highway runs along the northern edge of Bangor's center, then turns northeast, following the Penobscot River past Orono and Old Town. (Prior to the early 1980s, I-95 was a super two highway north of Old Town).
The highway continues north, still running near the river, toward Howland. Near Lincoln, I-95 runs north through uninhabited forest land, crossing the Penobscot River at Medway. The highway goes northeast and east, passing a series of small Aroostook County farming towns before reaching Houlton, where it connects to US 2 and New Brunswick Route 95 at the international border. North of Bangor, traffic levels drop noticeably, with an annual average daily traffic of only about 5,000 in northern Penobscot County and going down to as low as 2,000 to 4,000 in Houlton.[3]

The Maine Turnpike Authority (MTA) was created by the Maine Legislature in 1941 to build and operate a toll highway connecting Kittery and Fort Kent. In 1947, the first section of highway, designated the Maine Turnpike, opened between Kittery and Portland. In 1953, the MTA began construction on an extension to the state capital at Augusta using the former right-of-way of the Portland–Lewiston Interurban railway from Portland through West Falmouth.[5] The original turnpike was the largest construction project in the state's history until the construction of the extension, which opened to the public on December 13, 1955.[6]
The Maine Turnpike was the first highway in the nation that was funded using revenue bonds. It remains self-financed and does not receive funding from the state or federal government. When the first section opened in 1947, it was only the second long-distance superhighway in the US following the October 1940 opening of the Pennsylvania Turnpike. For these reasons, the Maine Turnpike was named a National Historic Civil Engineering Landmark by the American Society of Civil Engineers in 1999.[7]
In 1956, one year after the Portland–Augusta extension opened, Congress created the Interstate Highway System. The remaining sections to be built—from Augusta to Fort Kent—would be publicly funded freeways instead of toll roads under the MTA. Today, this highway, which ends at Houlton instead of Fort Kent, is signed as I-95 throughout and the Maine Turnpike between the New Hampshire line at Kittery and the junction with US 202 near Augusta.
In 2015, the MTA purchased the segment from the Piscataqua River Bridge to milemarker 2.2 of I-95 from the Maine Department of Transportation (MaineDOT).[citation needed]
The Maine Turnpike had a posted speed limit of 70 mph (110 km/h) in the early 1970s, but, as Maine then had no law against traveling less than 10 mph (16 km/h) over the posted limit, the de facto speed limit was 79 mph (127 km/h). In 1974, as part of a federal mandate, the speed limit was reduced to 55 mph (89 km/h), with a new law including a "less than 10 over" violation. In 1987, Congress allowed states to post 65 mph (105 km/h) on rural Interstate Highways. Following the relaxation, Maine increased its speed limit. In May 2011, a bill was introduced to raise the speed limit on I-95 from Old Town to Houlton from 65 to 75 mph (105 to 121 km/h). It passed, with Maine the first state east of the Mississippi River since the 1970s to establish a 75-mile-per-hour (121 km/h) speed limit.[8][9]
A further law passed in 2013 by the Maine Legislature allowed MaineDOT and the MTA to change speed limits with the approval of the Maine State Police. Per that law, MaineDOT increased the 65-mile-per-hour (105 km/h) limit to 70 mph (110 km/h) on several sections of I-95 on May 27, 2014. These areas included the section from milemarker 114 just outside Augusta to mile 126 just before Waterville. In addition, the section from Fairfield (just north of Waterville) to Bangor also saw an increase to 70 mph (110 km/h).[10] Speed limits on sections controlled by the MTA increased on August 11, 2014. The sections from milemarker 2.1 in Kittery to milemarker 44.1 in Scarborough and the section from milemarker 52.3 in Falmouth to milemarker 109 in Augusta increased from 65 to 70 mph (105 to 113 km/h). The section from milemarker 44.1 in Scarborough to milemarker 52.3 in Falmouth increased from 55 to 60 mph (89 to 97 km/h).[11]
The Maine Turnpike is a toll road for all of its length except south of York and between Auburn and Sabattus. Flat-fee tolls are paid upon entering the turnpike and at toll barriers in York, New Gloucester, and West Gardiner. As of November 1, 2021[update], it costs passenger vehicles $8.00 with cash and out-of-state E-ZPasses and $6.70 with a Maine issued E-ZPass to travel the entire length of the turnpike.[12] The turnpike joined the E-ZPass electronic toll collection network in 2005, replacing the former Maine-only system designated Transpass that was implemented in 1997.[13]
The tolls on the Maine Turnpike were not supposed to be permanent. Toll collections were to stop once the MTA paid off the debt from the road's construction. In the 1980s, the bonds were going to be paid off, but the Maine Legislature authorized the MTA in 1982 to continue as a quasigovernmental agency and to continue to collect tolls in order to fund the maintenance of the section of highway controlled by the MTA.[14]
There are eleven total rest areas on I-95 in Maine, five of which are full service plazas operated by the MTA. Five of the rest areas are accessible from northbound only, four are accessible from southbound only, and two are accessible from both directions. The rest stops are open 24 hours and all provide restrooms and visitor information. Food and fuel services as well as ATMs are available only at the five major plazas. The plazas are at the following locations:
There is a rest area and tourist welcome center located on the turnpike northbound at milepost 3 in Kittery. There are weigh stations located on the turnpike northbound and southbound in York at milepost 4 (southbound) and milepost 6 (northbound). There are ramps to and from the northbound turnpike to the Saco Ramada Hotel and Conference Center in Saco at milepost 35.[15] The ramps are from the original exit 5 which was replaced when I-195 was opened just to the north. The hotel was built on the site of the old toll plaza. Ramps connecting the hotel to and from the southbound turnpike were removed as part of the widening project in the early 2000s when hotel ownership opted not to pay nearly $1 million (equivalent to $1.55 million in 2023[16]) to build a new bridge. The MTA is planning to reestablish the exit at this location by 2022 in order to relieve traffic congestion at the intersection of I-195 and Industrial Park Road, which can often back up to I-95.[17]
North of Augusta, there are two additional pairs of rest areas before I-95's northern terminus in Houlton. Separate facilities are located on each direction of I-95 in Hampden, just south of Bangor; and in Medway, about halfway between Bangor and Houlton. There are 24-hour restrooms at all four locations, while the Hampden facilities each feature a state-operated Maine information center available during daytime hours. A final rest area, which also contained a state-operated Maine information center, was located in Houlton, and was accessible from both directions of I-95 by taking exit 302. The rest area has since been decommissioned and demolished as of mid-2022.[citation needed]
In 2019, MaineDOT began signing emergency routes along roads near I-95. The routes generally lead from one exit to the next exit and are meant to be used when sections of the highway must be closed due to an accident or other disruption. In such an event, electronic signs will be activated and flaggers deployed to direct drivers to use the appropriate emergency route to lead them around the closure and maintain traffic flow. Northbound routes are designated with a single letter, while southbound routes are designated with double letters. This system was first used when a section of highway was closed due to the death of a Maine State Trooper in an accident.[18]
