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.

[2] 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.

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.

Running through wooded areas, the highway approaches the Falmouth toll barrier, which charges $1.00 for passenger vehicles.

[citation needed] The turnpike stayed unnumbered between Falmouth and Gardiner until around 1988, when it was added to the Interstate System as I-495.

[12] The MaineDOT and Maine Turnpike Authority (MTA) decided not to sign or publicize I-495 to minimize confusion;[3] 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.
