The Maine Turnpike Authority will close a portion of the Falmouth spur for three weeks starting Monday.
The southbound off-ramp exiting the Maine Turnpike at exit 52 will be closed between March 18 until early April to allow the exit’s overpass bridge to be rebuilt, according to the authority.
The $3.5 million project will occur in phases. For one week in late May or early June, the on-ramp for southbound travelers will be closed, and starting around the same time, the southbound off-ramp will close again until November.
The work will replace the overpass deck concrete, side railings, and superstructure underneath. Engineers will also raise the bridge to allow for more clearance for traffic that passes below.
Southbound travelers are advised to use alternate routes, including I-295 at exit 45, exit 48 to Brighton Avenue, and exit 53 at West Falmouth to Route 100 and Washington Avenue.
