Massachusetts Route 7A

The southern segment begins at the Connecticut border, where the unsigned Connecticut State Road 832 connects Route 7A to its parent route 0.3 miles (0.48 km) south in the town of Canaan. Route 7A runs northward for three miles, through the village of Ashley Falls and crossing the Housatonic River before rejoining its parent route 3 miles (4.8 km) north of the state border.

The route then becomes silent for 22.7 miles (36.5 km), until US 7 reaches the town of Lenox. In Lenox, Route 7A splits with its parent route just south of US 7's junction with US 20. It heads northward, passing the Berkshire Performing Arts Center before sharing a brief, 0.2 miles (0.32 km) concurrency with Route 183. It then turns northward through Lenox Village along Main Street, ending finally at its parent route, one mile northward.

From its southern to northern ends, Route 7A is 25.3 miles (40.7 km) long. Its daylighted sections, however, only add up to approximately 5.6 miles (9.0 km). Both segments follow former alignments of their parent route. The northern segment follows along Route 7's former path, before it was given its bypass route around Lenox Village. The bypass was made as part of a failed attempt to make that route a freeway to Lanesborough.

The entire route is in Berkshire County.
