Interstate 495 - Falmouth Spur

Interstate 495Maine Turnpike

AASHTO approved the establishment of Interstate 495 over the Maine Turnpike mainline from West Falmouth to Gardiner on December 4, 1987. The toll road was previously unnumbered along this stretch.

The 2004 rerouting of Interstates 95, 295, and 495 in Maine resulted in the decommissioning of Interstate 495 along the Maine Turnpike mainline between the Falmouth Spur and Gardiner. That path is now a part of Interstate 95 between Portland and Augusta. I-95 originally followed a toll free highway south from Gardiner to Falmouth and the Maine Turnpike Falmouth Spur west to the Maine Turnpike mainline. With Interstate 295 following the original I-95 alignment between Falmouth and Gardiner, the 4.2 mile Falmouth Spur was redesignated as I-495. Since the spur acts as a connector between the two north-south routes, I-495 is unsigned with trailblazers for Interstates 95 and 295 posted for the route instead. The Falmouth Spur of the Maine Turnpike opened in conjunction with the turnpike mainline between Portland and Augusta in 1955.1
