 DelDOT has plans to widen DE 1 by an additional lane in each direction between the Chesapeake and Delaware Canal Bridge and the DE 273 interchange in Christiana . The project will involve widening bridges and reconfiguring interchanges . Construction is currently delayed due to funding issues . A project began on September 21 , 2015 to construct a northbound auxiliary lane between the US 40 and DE 273 interchanges in order to reduce congestion , which was completed shortly before Thanksgiving 2015 . On April 29 , 2016 , Governor Markell , DelDOT secretary Cohan , and local officials attended a groundbreaking ceremony for a $ 7 million project that will rebuild the DE 72 interchange into a diverging diamond interchange , the first such interchange in Delaware .
