Interstate 395 (I-395) is a auxiliary Interstate Highway in the U.S. state of Maine. The western terminus of the route is at a cloverleaf interchange with I-95 near downtown Bangor, where I-395 continues west as US Route 2 (US 2) and State Route 100 (SR 100). The eastern terminus is at US 1A in Brewer. Route description I-395 begins as an extension of Hammond Street at an at-grade intersection with US 2 and SR 100 on the south side of Bangor International Airport. US 2 and SR 100 turn north from the intersection onto Odlin Road, while I-395 reaches a cloverleaf interchange with its parent route, I-95, immediately to the east. The four-lane freeway is joined by SR 15 and travels east around the south side of Bangor, also becoming concurrent with US 202 near the Beal University campus. I-395 then intersects Main Street, carrying US 1A and US 202, near the Cross Insurance Center on the west side of the Penobscot River. The freeway crosses the Penobscot River on the Veterans Remembrance Bridge, which carries four through lanes and two auxiliary lanes from Bangor to Brewer. SR 15 leaves I-395 at a junction on the east bank of the river, while the freeway continues southeast through the outskirts of Brewer. I-395 travels into the rural outskirts of the Bangor area and turns northeastward to terminate at a partial cloverleaf interchange with Wilson Street (part of US 1A) east of Brewer. US 1A continues southeast towards the Down East region of the state, serving Ellsworth and several coastal towns. The freeway primarily serves as a bypass of Bangor and Brewer for travelers wishing to access the Down East/Bar Harbor region of Maine. It also connects I-95 to the region via US 1A. It is designated by the Maine state government as part of Highway Corridor Priority 1, which includes all Interstate Highways in the state as well as other important roads. Traffic volumes on the highway, measured in terms of annual average daily traffic by the Maine Department of Transportation (MaineDOT), ranged in 2017 from a minimum of 8,470 vehicles near its eastern terminus to a maximum of 17,090 vehicles on the Veterans Remembrance Bridge.
