Construction on the Pocomoke City–Snow Hill road was started from the Pocomoke City end in 1911. The first three sections were completed as macadam roads from Pocomoke City east to Outens Entrance in 1911, from Snow Hill west to Hardship Branch in 1912, and from Outens Entrance to Betheden Church in 1914. The final section, from Betheden Church to Hardship Branch, was constructed as a concrete road. The highway from the state-aid section on the north side of Berlin to Showell was constructed as a concrete road in 1917 and 1918. A concrete road was built north from Showell along a new alignment to tie in with the southern end of the DuPont Highway at Selbyville in 1921. By 1923, the town of Snow Hill resurfaced its Main Street and turned it over to the Maryland SRC, and Berlin gave its concrete Main Street to the state for maintenance, completing the highway from Pocomoke City to the Delaware state line.
