Delaware State Route 9A joins Interstate 495, U.S. 13 and SR 9 with the Port of Wilmington. The south leg follows Terminal Avenue east from SR 9 (New Castle Avenue) at the Eden Park Gardens community, to a parclo interchange with I-495 and the port entrance. Christina Avenue angles the state route northwest to U.S. 13/SR 9 (Heald Street) in the Southbridge neighborhood of Wilmington.

The 2015 Delaware Vehicle Volume Counts list only references the 0.78 mile section of SR 9A on Terminal Avenue. The Christina Avenue segment is not inventoried as a state route. The route is also not acknowledged from U.S. 13/SR 9 on Heald Street.

SR 9A was designated in 1970, when SR 9 was extended north from New Castle Avenue to 4th Street west through Wilmington. The state route along Christina Avenue overlays the historic alignment of SR 48, which connected the Heald Street Bridge with the Wilmington to Penns Grove Ferry landing until 1951.
