Delaware Route 71

Delaware Route 71 (DE 71) is a state highway in New Castle County, Delaware. The route loops off U.S. Route 13 (US 13) from south of Townsend to Tybouts Corner, traveling to the west of US 13 by way of Townsend, Middletown, and the Summit Bridge. The route overlaps US 301 from the north end of Middletown to just north of the Summit Bridge, and also with DE 896 from Mount Pleasant to just north of the Summit Bridge, where US 301 and DE 896 continue north together to Glasgow.

DE 71 was built as a state highway during the 1920s and 1930s. By 1938, the route was designated to run from US 13 south of Townsend to US 13 in Tybouts Corner roughly along its present-day alignment. In the 1950s, DE 71 was rerouted to head to the Maryland border southwest of Middletown, with the former route south of Middletown becoming an extended DE 896. Between the 1950s and 1980s, DE 71 was signed with various alignments of US 301 and US 301S. In the 1980s, DE 71 was truncated to DE 896 in Summit Bridge before being extended back along its 1930s alignment to US 13 by the 1990s.
