 DE 896 was originally built as a state highway during the 1920s and 1930s. By 1938, the route was designated between DE 71 in Summit Bridge and the Maryland border northwest of Newark. In the 1950s, the route was extended to US 13 south of Townsend, following DE 71 to Middletown and replacing a part of that route south of there. Between the 1950s and 1990s, various alignments of US 301, US 301N, and US 301S followed DE 896. In the 1980s, DE 896 was realigned to head from Mt. Pleasant to US 13 in Boyds Corner, with DE 71 later being extended down the former route past Middletown. Also around this time, DE 896 was rerouted to bypass the University of Delaware to the west. A bypass of Glasgow was completed in the 1990s.
