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 toll road was constructed between Dover and the Wilmington metropolitan area. Explosive growth continued through the new millennium with 935,614 Delawareans estimated per the Census in 2014.

The 14-mile long U.S. 301 toll road opened to traffic on January 10, 2019. Other projects expand existing roadways, modify interchanges, and replace intersections along both U.S. 113 and State Route 1 with grade separations.
