Signed by the Governor on March 27, 2002, the Maine Legislature passed a bill redesignating parts of the Interstate system and renumbering all of the exit numbers from a sequential to a mileage based system. The intent of the redesignation was to:
- designate the entire length of the Maine Turnpike as I-95 which will provide a continuous routed Interstate which reduces confusion for motorists
- lengthen the existing 1-295 through greater Portland so that it runs all the way to Gardiner where it reconnects with I-95
- eliminate the 1-495 designation
The American Association of State Highway and Transportation Officials (AASHTO) approved the route numbering applications to redesignate I-495 along the Maine Turnpike as Interstate 95 and extend Interstate 295 north over former I-95 to Gardiner on October 11, 2002. Prior discussion between AASHTO, the Maine Department of Transportation and the Federal Highway Administration (FHWA) regarding the unnumbered Falmouth Spur resulted in an amendment made to the application designating it as Interstate 495.
A $12.2 million project from June to December 2010 repaved all of the southbound lanes for Interstate 295 from the Maine Turnpike spur in Falmouth south to the toll plaza at Scarborough. The project also included resurfacing 18 bridges and repairing them as needed and making safety improvements around the Franklin Street interchange (Exit 7). A coinciding $8.4 million project rebuilt the northbound lanes from the south Falmouth town line to Freeport. That work was completed by the end of October 2010.3
