Maryland Route 2 (MD 2) is the longest state highway in the U.S. state of Maryland. The route runs from Solomons Island in Calvert County north to an intersection with U.S. Route 1 (US 1) and US 40 Truck (North Avenue) in Baltimore. The route runs concurrent with MD 4 through much of Calvert County along a four-lane divided highway known as Solomons Island Road, passing through rural areas as well as the communities of Lusby, Port Republic, Prince Frederick, and Huntingtown. In Sunderland, MD 2 splits from MD 4 and continues north as two-lane undivided Solomons Island Road into Anne Arundel County, still passing through rural areas. Upon reaching Annapolis, the route runs concurrent with US 50 and US 301 around the city. Between Annapolis and Baltimore, MD 2 runs along the Governor Ritchie Highway (also known as the Ritchie Highway), a multilane divided highway that heads through suburban areas of businesses and residences, passing through Arnold, Severna Park, Pasadena, Glen Burnie, and Brooklyn Park. In Baltimore, the route heads north on city streets and passes through the downtown area of the city.
