The Cornish-Windsor Bridge was built four times. The last time, in 1866, they got it right. At 407 feet across, it is the longest covered bridge in the United States, and the longest two-span covered bridge in the world. The bridge has been closed, repaired and reopened several times, but it still stands, connecting Vermont and New Hampshire over the Connecticut River. It is designated as a National Historic Civil Engineering Landmark and is on the National Register of Historic Places.
