The Swift River Bridge, built in 1870, replaced an earlier bridge that had a most interesting demise. The first bridge was built by John Douglass in 1850. In 1869, heavy rain caused the river to rise lifting the bridge off of its foundation. The current turned the bridge and sent it downstream.
Unfortunately, the Saco River Bridge is only a short distance downstream from this bridge. The Swift River Bridge careened downstream crashing into the Saco River Bridge, knocking it off its abutment. Both bridges broke up in the current and came to rest two miles downstream.
People in New Hampshire are a frugal bunch. They salvaged the broken-up pieces of wood and used them in re building this bridge. The new bridge was built by Jacob Berry and his son Jacob. Standing on the riverbank directly below this bridge, one can see the Swift River Bridge to one side and the Saco River Bridge on the other.
