Delaware Covered Bridges of Delaware State Delaware state never had many covered bridges, and its few were located in the northern part of the state, in New Castle County, near the Pennsylvania line.
Ferries are better in that kind of country.
But Delaware has used, and does use, covered bridges to cross some of its northern creeks, especially the Red Clay and the Brandywine. In flood it certainly seems a river. And for that reason, the Brandywine bridges have been set high above the creek. Here is a picture of one, from an early picture post-card. The Bridge at Rising Sun Rising Sun seems to have been near the Du Pont powder works, now the Hagley Museum.
