MD 370 begins at an intersection with MD 33 (St. Michaels Road) a short distance west of the town of Easton. The state highway heads northwest as a two-lane road through a mix of farmland and residential subdivisions. MD 370 crosses the Miles River on a bascule drawbridge before reaching its northern terminus at an intersection with Miles River Road near Unionville. Unionville Road continues north as a county highway toward the center of Unionville and Tunis Mills.
The original Miles River Bridge was constructed as a state-aid project in 1913, along with 2 mi (3.2 km) of roads connecting the bridge to Unionville and Tunis Mills. The bridge was connected with a modern road to MD 33 by 1933. The original Miles River Bridge was replaced by the present bridge in 1984.
The entire route is in Talbot County.
