Between the 1960s and the 1980s, MD 2/MD 4 between Solomons and Sunderland was widened into a divided highway, with the bypassed former alignments becoming multiple sections of MD 765. The Ritchie Highway portion of the route was originally the main route between Annapolis and Baltimore until Interstate 97 (I-97) was completed in the 1990s. Route description MD 2 serves as a north–south route located a short distance to the west of the Chesapeake Bay in Calvert and Anne Arundel counties and in the city of Baltimore in Maryland. In Calvert County, the route runs through mostly rural areas, passing through the communities of Solomons Island, Lusby, Port Republic, Prince Frederick, Huntingtown, Sunderland, and Owings. Between Solomons Island and Sunderland, the route runs concurrent with MD 4. In Anne Arundel County, MD 2 runs through rural areas of the southern part of the county before reaching the Annapolis area, where it shares a concurrency with US 50/US 301 on the John Hanson Highway.

A short distance later, a portion of MD 765 called MD 765R continues north along Solomons Island Road, while MD 2 merges onto MD 4 at an interchange to form a concurrency with that route on a four-lane divided highway a short distance north of where MD 4 crosses the Patuxent River over the Governor Thomas Johnson Bridge. Upon merging with MD 4, the road continues north as Solomons Island Road, passing commercial areas to the east and a U.S. Navy Recreation Center to the west.
