History

The Falmouth Spur was built as part of the second phase - Portland to Augusta - of the Maine Turnpike, opened December 13, 1955, as well to allieviate traffic on Falmouth Road, the town's east to west connector, connecting Route 9 (Middle Road) and Routes 26 and 100 (Gray Road). The spur connected interchange 8, a trumpet interchange with the mainline Turnpike, with interchange 9, another trumpet at U.S. Route 1 in Falmouth. (The west end later became exit 9 - exit 8 was moved south to the new Westbrook interchange - and the east end became exit 15 on I-95.) The toll booth was just west of US 1, right where the Spur now crosses over Interstate 295

. The part of US 1 that it connected to had been built ca. 1948 as a realignment (old US 1 is Route 88), and the Spur connected the Turnpike, which headed inland at Portland, with US 1, a major route to and beyond Brunswick via the shore.

The Turnpike stayed unnumbered between Falmouth and Gardiner until around 1988, when it was added to the Interstate System as I-495. This allowed it to have a speed limit

 submitted a proposal to the American Association of State Highway Officials to relocate I-95 along I-495 and extend I-295 along I-95 to Gardiner, leaving the Falmouth Spur unnumbered. This was approved by AASHTO on November 5, 2002, with one change - the Falmouth Spur was assigned the Interstate 495 designation. The Maine DOT and Maine Turnpike Authority decided not to sign or publicize I-495 to minimize confusion; maps of the changes distributed to the public included the remark "existing I-95 becomes a ramp" or just "Falmouth Spur" pointing to the Spur. Signs were changed from January 5 to January 10, 2004 A prominent sign was posted near the New Hampshire state line informing travelers of the change, and that the information center had new maps.
