In December 1995, the section of DE 1 between US 13 in St. Georges and US 13 in Tybouts Corner opened, which included the Chesapeake & Delaware Canal Bridge (now called the Senator William V. Roth Jr. Bridge). Following the completion of this segment, DE 1 was rerouted off the surface alignment of US 13 that crossed the St. Georges Bridge. Subsequently, US 13 was rerouted to follow the new DE 1 between the DE 72 interchange and Tybouts Corner. Construction of the new DE 1 had severed US 13 south of Tybouts Corner, with part of the former alignment north of the DE 7 intersection becoming a two-lane road called Old South Dupont Highway using the southbound lanes, with the northbound lanes abandoned, while the section south of there became an extended DE 7 to the intersection with US 13 and DE 72. In building DE 1 across the Chesapeake & Delaware Canal, there were initially plans to demolish the aging St. Georges Bridge that carried US 13 over the canal. The plan drew concerns from residents in St. Georges who feared the community would be split in half. The St. Georges Bridge was instead kept and was refurbished. A southbound exit and northbound entrance at US 13 south of the Chesapeake & Delaware Canal Bridge along DE 1 was built as required by federal legislation that gave the state $115 million toward construction of the new canal bridge.
