MD 262 was constructed as a gravel road from MD 2 in Sunderland starting in 1924. The state highway was built to just west of Chew Creek in 1927. MD 262 was completed to Lower Marlboro in 1928. Aside from maintenance and paving, the state highway changed very little until 2003, when a directional crossover intersection was constructed at MD 4. The section of Lower Marlboro Road between MD 4 and MD 2 was redesignated MD 262A.
