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 and 989,948 in the 2020 Census.

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.

A number of photos from the early Delaware Highways Pages appear in the I’m from Delaware music video:

The original pages were compiled from 1998 to 2004, mostly from personal observation and recollections of news paper articles and library research from the webmaster.
