 In the 1970s, the MassDPW changed the planned designation of the unconstructed Route 25 expressway northwest of Route 24 to I-495.When this portion of I-495 was completed in 1982, the state also designated the existing alignment of Route 25 between Route 24 and the I-195 interchange in Wareham as I-495.After the reassignment, Route 25 was shortened to a stretch from I-195 east to Downtown Wareham.
