At 244 feet this was the longest span bridge in the United States when it opened. Timothy Palmer was the engineer / bridge builder who designed and built the bridge. Palmer was a pioneer in long span wooden truss bridge design and had already constructed several bridges in Massachusetts. The bridge was essential in establishing the first NH turnpike a land route between Portsmouth and Boston. This was an important bridge in early American bridge design and construction.
