History
A prior, one lane wooden suspension bridge known as "Zoar Bridge" existed just south of the confluence of the Halfway River with the Housatonic, at what is now the Monroe/Newtown town line, about 3/4 mile upstream from the dam/bridge current location. The supports for the old bridge were inundated with the construction of the dam. This bridge was not the predecessor to the current Derby-Shelton Bridge. In the winter of 1875, a flood carried Zoar Bridge a mile down stream. In 1890, county commissioners ordered the removal of a toll house connected to the Oxford side of the bridge, as it was deemed a fire hazard.Renovations
