Welcome to Delaware Highways!

The Delaware Highways page is intended to give an overview of the Delaware state highway system. Included are photos, historical information, maps, and traffic counts covering the roads of the First State.

A doubling of the state population since 1970 brought the total to 786,189 as of the 2000 census. During that time period, Interstate 95 expanded from six to eight lanes, tolls at the Delaware Turnpike interchanges were removed, and the SR 1 Turnpike was constructed between Dover and the Wilmington metropolitan area. Explosive growth continued through the new milenium with 935,614 Delawareans estimated per the Census in 2014.

Projects continue to expand existing roadways while construction is underway to build a new toll road for U.S. 301 and upgrade several at-grade intersections along Delaware 1 to full interchanges. Future work may also expand portions of U.S. 113 to expressway standards.
