two years before US 13 had been completed as a four-lane divided highway from Dover to Wilmington, Delawareans petitioned DSHD to extend the divided highway south to the Maryland state line at Selbyville or Delmar (US 13), a proposition DSHD acknowledged but deferred due to lack of funding, lack of proper planning, and higher priorities elsewhere in the state. Instead of adding divided highway in southern Delaware, DSHD needed to resolve the problem of the deterioration of 15- to 25-year-old concrete roads, such as those along the DuPont Highway. The department planned to address the issue by patching the concrete surface as needed, adding concrete shoulders, and applying a layer of bituminous concrete, more commonly known as asphalt concrete or blacktop, over the entire width of concrete to provide a wearing surface. 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. In 1934, MDSRC had recommended widening the entirety of US 113 from to . Aside from the Pocomoke City Bypass, widening and reconstruction of the U.S. Highway in that state did not occur until after World War II. US 113 was widened and resurfaced from the north end of Berlin to the Delaware state line in 1947 and 1948 and from Pocomoke City to south of Snow Hill in 1948. The highway through Berlin was resurfaced in 1949. The U.S. route from the north end of Snow Hill to Newark was widened and resurfaced in 1951 and 1952. State forces reconstructed or widened seven bridges along the
