Falmouth Spur

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.
