The first highway to be so treated was US 113 from Frederica to Little Heaven, which was resurfaced and widened to in 1941. DSHD included the highways between Dover and Milford and between Milford and Selbyville among those that should be reconstructed and resurfaced in the following four years, but that work was postponed due to the near-total cessation of highway construction projects during United States involvement in World War II. DSHD was able to resume this mode of highway reconstruction, which also included widening bridges and culverts, in 1944. This reconstruction plan returned to US 113 in 1946, when the highway between Ellendale and Georgetown was placed under reconstruction. The sections from Selbyville to Dagsboro, from Dagsboro to Georgetown, and from Milford to Little Heaven were expanded beginning in 1947. The post-war reconstruction and widening of US 113 to from Selbyville to the Dover Bypass in Little Heaven was completed with work on the U.S. Highway's Ellendale–Milford segment in 1949.
