In May 2011, Sussex County legislators proposed the U.S. Highway be upgraded fully along its current alignment, with the addition of a northeast bypass of Millsboro to connect US 113 and DE 24 that could be constructed mostly through state-owned land. Despite opposition to its preferred alternative, DelDOT completed the Draft Environmental Impact Statement for the Millsboro–South area in July 2013; the document recognized the significant opposition to the Blue Alternative. In 2015, DelDOT announced that the Blue Alternative was no longer being considered. Instead, US 113 would be upgraded along its current alignment as part of a Modified Yellow Alternative. However, unlike the original Yellow Alternative, which would upgrade US 113 to a freeway and featured several interchanges, US 113 would not become a freeway under the modified plan. Instead, only some crossroads would be eliminated, US 113 would be expanded to six lanes between its intersections with DE 20 on either side of Millsboro, and a two-lane northeast bypass of Millsboro proposed in 2011 would be built and connect with US 113 at a partial cloverleaf interchange near the northern US 113–DE 20 junction. In December 2016, DelDOT completed a Supplemental Draft Environmental Impact Statement in which the Modified Yellow Alternative is the agency's preferred alternative.
