Route description
Route 102 begins in West Stockbridge at the New York state line. It continues into Canaan, New York to meet New York State Route 22 (NY 22) via a 0.2 mi connector road. The road, maintained by the New York State Department of Transportation, is designated NY 980D, an unsigned reference route.

The route crosses Interstate 90 (Massachusetts Turnpike) twice in its first 2 mi, where it is also known as State Line Road. It joins Route 41 for a 1/2 mi concurrency through the center of West Stockbridge, crossing the Williams River south of Shaker Mill Pond. The concurrency ends just north of exit 3 of the Mass Pike, which provides access to the eastbound turnpike and from the westbound turnpike.

Following this intersection, the route continues east into Stockbridge as West Stockbridge Road. It crosses the Mass Pike once more before intersecting Route 183 – which serves the Berkshire Botanical Garden and Norman Rockwell Museum – in the Larrywaug section of town.

The route passes through the center of the town by way of Church Street and Main Street, passing concurrently with U.S. Route 7 (US 7) for 1/4 mi. The route then continues eastward via Pleasant Street, traveling parallel to the Housatonic River as it continues into Lee. After an at-grade railroad crossing with the Berkshire Subdivision, the route turns to the northeast before meeting its eastern terminus at the junction of US 20 (Houstatonic Street) and the entrance ramps to exit 10 of the Mass Pike.
