Delaware 9A


Delaware 9A joins Interstate 495, U.S. 13 and Delaware 9 with the Port of Wilmington. The south leg follows Terminal Avenue east from Delaware 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 & Delaware 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.

Delaware 9A was designated in 1970, when Delaware 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 Delaware 48, which connected the Heald Street Bridge with the Wilmington to Penns Grove Ferry landing until 1951.

Passing under the high level bridge carrying Interstate 495 across the Christina River. The span closed in June 2014 due to tilting of four support columns. An estimated 55,000 tons of dirt stored at a site beside Christina Avenue caused the failure. Emergency work through the end of 2014 stabilized the supports and corrected the span level. Photo taken 08/10/04.
