The state highway was designated when MD 36 moved to a new alignment through the community in the early 1980s.

MD 937 begins at an intersection with MD 135 (Church Street) adjacent to the junction of the Georges Creek Railway with CSX's Thomas Subdivision railroad line on the south side of Westernport.

North of downtown Westernport, MD 937 passes through several sharp curves as it parallels the Georges Creek Railway.

The state highway passes a row of residences before reaching its northern terminus at MD 36 (New Georges Creek Road).

[3] MD 36's present alignment on the west side of Georges Creek was under construction by 1975.
