Blair Bridge was originally built in 1829, and was destroyed by an arsonist. The present bridge was erected in 1870, and includes one (1) timber from the original bridge. At 292′ 10″, it’s the 2nd longest covered bridge entirely within the boundaries of the state. It has two (2) spans, and is of “long truss with arches” type of construction. The four (4) corners were rebuilt in 1977 by the famous Milton Graton. The Blair Bridge is the last remaining in New Hampshire constructed using Long’s patented truss design.
