U.S. 13 Business was commissioned in 1970 over the former mainline of U.S. 13 through Wilmington and Claymont in northern New Castle County. AASHTO approved the renumbering on November 6, while approving the reroute of U.S. 13 over what was U.S. 13 Alternate to the east. Prior to the renumbering through Wilmington, U.S. 13 north followed Walnut Street north and 16th Street west. This alignment doubled as U.S. 202 north, which combined with U.S. 13 from State Road to Concord Avenue in north Wilmington. U.S. 13 south used Market Street south from 16th Street to 14th Street east. French Street carried the route south to 2nd Street, which returned U.S. 13 west two blocks to Market Street south. U.S. 202 south overlapped with U.S. 13 south from Front Street. French Street no longer exists between East 2nd and East 8th Streets.
U.S. 13 Business begins at Rogers Corner and the confluence of I-495, Rogers Road, Market Street and Heald Street. Heald Street leads U.S. 13 northeast to Southbridge in Wilmington while U.S. 13 Business lines South Market Street to Garasches Lane and the Wilmington city line. North from there, U.S. 13 partitions into a one-way couplet using Walnut Street north and Market Street south. Both streets span the Christina River along double-leaf bascule bridges.
U.S. 13 Business north remains wholly along Walnut Street from the Christina River through the Wilmington central business district and East 16th Street. U.S. 13 Business south meanwhile follows King Street from East 16th Street to Martin Luther King Boulevard (SR 48) west and Market Street south by the Wilmington Train Station. The couplet recombines with U.S. 13 Business turning west two blocks on 16th Street to King Street at the Market Street Bridge across Brandywine Creek.
Market Street angles U.S. 13 Business northeast through Brandywine Village and the Eastlawn communities in north Wilmington. The route narrows to just two lanes to Lea Boulevard and the Wilmington city line. North from there, U.S. 13 Business expands into a four-lane boulevard (Philadelphia Pike) by the town of Bellefonte, Holly Oak and Claymont. U.S. 13 overtakes Philadelphia Pike from Governor Printz Boulevard just ahead of the interchange with Interstate 495.
