- 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.
