Below is a list of covered bridges in Delaware. There are only three authentic covered bridges in the U.S. state of Delaware of which two are historic. [1] A covered bridge is considered authentic not due to its age, but by its construction. An authentic bridge is constructed using trusses rather than other methods such as stringers, a popular choice for non-authentic covered bridges.
