U.S. Route 113 Alternate (US 113 Alternate) was an alternate route of US 113 that extended from US 113 and DE 1 in Little Heaven north to the intersection of US 13 and US 113 in Dover. US 113 Alternate followed the original path of the DuPont Highway between Little Heaven and US 13 in Dover. The DuPont Highway was paved through Rising Sun by 1920, and the entire length of the Selbyville–Wilmington highway was complete by 1923. When the U.S. Highway System was finalized in 1926, US 113's northern terminus was at Coopers Corner south of Dover, and US 13 followed State Street through the state capital. US 113 was extended north along State Street to the junction of State Street and Governors Avenue on the south side of Silver Lake after US 13 was placed on a reconstructed Governors Avenue in 1930. After US 113's bypass of Dover was completed in 1935, US 113 Alternate was established along US 113's former course from Little Heaven to Dover and along State Street and joined US 13 to cross Silver Lake to reach US 113's northern terminus at the intersection of DuPont Highway and State Street.
