Interstate 495 (I-495) is the unsigned designation for the Falmouth Spur, a short freeway connecting I-95 with I-295 and U.S. Route 1 (US 1) north of Portland, Maine, in the United States. As part of the Maine Turnpike, the main line of which carries I-95, I-495 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[4]—to minimize driver confusion.[5]

Prior to January 2004, I-495 was a 50.47-mile-long (81.22 km)[6] section of the Maine Turnpike, running from the west end of the Falmouth Spur (which carried Interstate 95) north to the present junction with I-295 at Gardiner (south of Augusta). This was re-signed as I-95 in order to designate the whole turnpike as I-95 and thus reduce confusion.[7] 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 Interstate 495 designation.

Destinations on signs (control cities) 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 I-495.[4]

MUTCD-compliant mile markers 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.

History

The Falmouth Spur was built as part of the second phase—Portland to Augusta—of the Maine Turnpike, opened December 13, 1955,[8] as well to allieviate traffic on Falmouth Road, the town's east to west connector, connecting State Route 9 (SR 9, Middle Road) with SR 26/SR 100 (Gray Road). The spur connected interchange 8, a trumpet interchange with the mainline turnpike, with interchange 9, another trumpet at US 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 I-295.[9][10] The part of US 1 that it connected to had been built c. 1948 as a realignment (old US 1 is SR 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.[11]

When the Interstate Highway System was designed in the 1940s and 1950s, the main route along the east coast, numbered I-95 in 1957, was assigned to the route via Brunswick to Augusta. Thus the Falmouth Spur became I-95, and the turnpike was unnumbered between the spur and Gardiner. Around 1960, the piece of I-95 (now I-295) north of the spur was completed, and a partial interchange was added at its crossing with the spur.[11] The toll booth was moved west at that time.[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] This allowed it to have a speed limit higher than the National Maximum Speed Limit of 55 miles per hour (89 km/h), as per the Surface Transportation and Uniform Relocation Assistance Act of 1987.[citation needed]

In 2002, the Maine Department of Transportation (Maine DOT) submitted a proposal to the American Association of State Highway Officials (AASHTO) 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 I-495 designation.[1] The Maine DOT and Maine Turnpike Authority decided not to sign or publicize I-495 to minimize confusion;[5] 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 10, 2004.[2][7] A prominent sign was posted near the New Hampshire state line informing travelers of the change, and that the information center had new maps.[4]
