Route description

Looking eastward from the Sandwich Road Bridge

The highway begins at exit 12 off Route 3, a partial interchange which is accessible only from the southbound side from which there is a left exit. Motorists on Plimoth Patuxet Highway headed toward Route 3 can enter that highway northbound only. However, motorists can use exit 13 to reverse direction and travel southbound on Route 3. The highway proceeds east, serving Plimoth Patuxet, Plymouth Beach and the village of Chiltonville. The highway ends at a special intersection in White Horse Beach and Manomet at Route 3A.

History

Looking westward from the Sandwich Road Bridge

The first segment of Route 3 opened up in 1951 from what is now exit 18 to exit 12 and used the Plimoth Patuxet Highway temporarily to detour around the old Route 3 in Kingston and Plymouth, now renamed Route 3A, until 1957 when Route 3 south of exit 12 opened and assumed its current alignment. An act naming the two-mile (3.2 km) spur Plimoth Plantation Highway was approved on April 3, 1969, 18 years after the highway had opened.^[2] That act references the highway as being exit 40, the old exit number before the Massachusetts Highway Department renumbered the exit in 1978.^{[citation needed]} The highway was renamed again to Plimoth Patuxet Highway effective January 2, 2023.^[3]
