MD 370 connects Easton with the northwestern Talbot County villages of Unionville and Tunis Mills, which are separated from the county seat by the Miles River.

A park and ride lot is located at the northwest corner of this intersection.

The state highway heads northwest as a two-lane undivided 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.

[1][2] 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.
