The route runs from DE&nbsp;273 in Pleasantville northeast to U.S. Route&nbsp;202 (US&nbsp;202)/DE&nbsp;141 north of the Wilmington Airport near Wilmington Manor. The road runs through suburban neighborhoods and passes along the edge of Wilmington Airport along Airport Road before it provides access to a business park along Commons Boulevard. The Airport Road portion of DE&nbsp;37 was originally a dirt road that was paved by 1942. DE&nbsp;37 was assigned to its current alignment by 1985.
