As part of building DE 1, the Puncheon Run Connector was proposed to provide a connection between DE 1 and US 13 in the southern part of Dover. The original plan for the connector in 1987 called for upgrading US 13 into a freeway between Woodside and Dover, with interchanges at DE 10 in Camden and Webbs Lane in Dover. In 1992, plans for the freeway upgrade to US 13 between Woodside and Dover were dropped. On December 21, 1993, DE 1 was completed between US 113 at Dover Air Force Base and US 13 north of Smyrna, with DE 1 rerouted off US 13 between Dover and Smyrna.
