MD 337 (Allentown Road) is a state highway that runs on the west and north sides of Joint Base Andrews (formerly Andrews AFB). It begins at an interchange with MD 5 and continues along the western periphery of Andrews AFB where the West Gate and Vistors Gate are accessible. MD 337 then merges onto Suitland Parkway, running concurrent with it to MD 4. Northbound MD 337 has a direct ramp onto Suitland Parkway, whereas southbound traffic has to take Foresville Road to Allentown Road; this is due to a weird quirk in the construction of both Allentown Road and Suitland Parkway in the 1990's.

MD 337 intersects MD 3 Business (Crain Highway) just a little over 600 feet ahead of MD 2. MD 2's current alignment on Governor Ritchie Highway was constructed throughout the 1930's and was to run parallel just a few hundred feet from Crain Highway through Glen Burnie, explaining why these intersections are so close to one another. MD 337 ends at MD 3 Business as it has since its completion in the early 1930's.
