Dalton Covered Bridge (#12)

We finally sent my soggy Canon Rebel XSi to Canon for repairs. Once the cold weather set in in October, it simply would not work. I took these photographs with the new Olympus Tough 8000 that I had never bothered to learn how to use.

Dalton Bridge is in Warner, New Hampshire in the old village, and crosses the Warner River.

Historical Remarks:
The structure was built by Joshua Sanborn. George Sawyer and Walter S. Davis built the abutments. Repairs were made to the bridge in 1871 at a cost of $134.81. In 1990, the state repaired the diagonal and the portal, and installed a new metal roof. There has been some debate as to the classification of the truss system. The Warner Historical Society in its 1974 publication, Warner N.H. 1880-1974, classified the bridge as a Haupt-type truss. the New Hampshire Department of Transportation indicates a classification of multiple Kingpost with an auxiliary Queenpost system. However, based on the National Register of Historic Places nomination form, it would appear to be classified as a Long truss with an auxiliary queenpost system. This is one of the oldest standing covered bridges in use today. It is also known as the Joppa Road Bridge. The bridge was rebuilt in 1963-1964. The rebuilding costs were shared by the town and the state. The Dalton Bridge is listed on the National Register of Historic Places.
