Interstate 395 Maine

Interstate 395 shares a brief overlap with U.S. 202 between Exits 2 and 3 south of Downtown Bangor. The western end connects to U.S. 2/Maine 109 as the Industrial Spur.


An east-west freeway from U.S. 1A to U.S. 2 and Interstate 95 constitutes the routing of Interstate 395. The highway sees several interchanges serving the downtown Bangor and Brewer municipal areas. The 3-digit Interstate is the last Interstate 95 northbound encounters on its trek to New Brunswick.

High Priority Corridor

Interstate 395 in Maine is part of High Priority Corridor 50: East-West Corridor from Watertown to Calais in its entirety.

Future Aspirations

Interstate 395 is being studied for a possible extension east to connect with Maine 9/The Airline to improve travel between Maine and the Canadian Maritime Provinces (New Brunswick, Nova Scotia, Prince Edward Island). According to preliminary reports, there are two possible corridors. The Maine Department of Transportation (from April 2004) supports the first corridor, which entails an extension of Interstate 395 that would be approximately two miles long, extending Interstate 395 east along the southern side of Alternate U.S. 1 to Holden. From Holden, the corridor would turn northward through mostly unpopulated areas until meeting Maine 9 near East Eddington, bypassing the town, and rejoining Maine 9 just west of Clifton. This segment (from Holden to Clifton) would not necessarily be constructed to Interstate standards immediately, but may be upgraded as traffic conditions warrant. An alternative route of this corridor would also extend Interstate 395, but it would take Interstate 395 from its current Wilson Street junction and follow the Holden-Brewer town lines until entering Eddington and connecting with a rebuilt Maine 9. Once the preliminary studies are complete, a corridor will be chosen for design and construction.1


Interstate 395, also known as the "Bangor Industrial Spur," was opened in stages. The first section opened between Main Street to Odlin Road in 1959. The extension from Bangor to Brewer opened to traffic in 1986.2
