The official designation of the route runs 0.78 miles (1.26 km) along Terminal Avenue between DE 9 and the Port of Wilmington, interchanging with I-495. Signage has the route continuing north along Christina Avenue to an intersection with U.S. Route 13 (US 13) and DE 9 for a total length of 2.0 mi (3.2 km).
