MD 242 was constructed as a gravel road from Morganza to Avenue by 1921 and completed to Coltons Point in 1923. The state highway was reconstructed with curve modifications and a bituminous-stabilized gravel surface in the 1950s, beginning with the Morganza–Clements section in 1949 and 1950. MD 242 was rebuilt from Clements to Bushwood by 1959.
