The Falmouth Spur is a short freeway connecting Interstate 95 (I-95) with I-295 and US Route 1 (US 1) north of Portland, Maine, in the United States. It carries the unsigned designation of Interstate 495 (I-495). As part of the Maine Turnpike, the mainline of which carries I-95, the Falmouth Spur is a toll road. The spur has only two interchanges—one at each end—and a toll booth in the middle. It is signed only for its destinations—I-95, I-295, and US 1—to minimize driver confusion. Prior to January 2004, the Falmouth Spur carried I-95 from the Maine Turnpike mainline to the spur's eastern terminus, where I-95 continued north along present-day I-295. In 2004, I-95 was rerouted to follow the entire length of the turnpike in order to reduce confusion. Most of the former I-95 between Portland and Augusta became an extension of I-295, while the short Falmouth Spur was given the unsigned I-495 designation. Destinations on signs (control cities) on the Falmouth Spur are the same as when it was part of I-95—Falmouth and Freeport for eastbound traffic from I-95 and Lewiston and Kittery (one for each direction of the turnpike) for westbound traffic from US 1. Signs on I-295 southbound point traffic for New Hampshire, Massachusetts, and "points south" along the spur. Manual on Uniform Traffic Control Devices-compliant milemarkers proceed easterly from the western end with the letters FS (for Falmouth Spur) horizontally on a line below the word "MILE" and range from 0 to 3. Route description The Falmouth Spur begins in the northwestern edge of Portland at a trumpet interchange with I-95 (Maine Turnpike) at exit 52. It heads east as a four-lane controlled-access highway, passing under State Route 100 (SR 100) with no access. The spur then crosses the Presumpscot River and passes under Falmouth Road. Running through wooded areas, the highway approaches the Falmouth toll barrier, which charges $1.00 for passenger vehicles. One express E-ZPass lane and two conventional toll lanes are provided in each direction. After the toll plaza, the Falmouth Spur passes under SR 9 and reaches its eastern terminus at I-295 and US 1. There is no exit from the Falmouth Spur to I-295 southbound nor is there an entrance from I-295 northbound. 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 alleviate traffic on Falmouth Road, the
