Plimoth Plantation Highway
Formed:	1951
From:	Route 3 in Plymouth
Major junctions:	none
To:	Route 3A in Plymouth

Plimoth Plantation Highway is a short unnumbered two-lane freeway with plastic stanchions posted on a rumbled asphalt median in Plymouth, Massachusetts. It begins at Exit 4 off Route 3, a partial interchange which is accessible only from the southbound side from which there is a left exit. Motorists on Plimoth Plantation Highway headed toward Route 3 can enter that highway northbound only. Exit 5 is nearby in order to reverse direction on Route 3. The highway serves the village of Chiltonville and Plimoth Plantation and heads toward White Horse Beach and Manomet via Route 3A.

The first segment of Route 3 opened up in 1951 from what is now Exit 9 to Exit 4 and used Plimoth Plantation 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 4 opened and assumed its current alignment. An Act naming the two-mile spur Plimoth Plantation Highway was approved on April 3, 1969, 18 years after the highway had opened. The Act references the highway as being Exit 40, the old exit number before the Massachusetts Highway Department renumbered the exit in 1978.
