History
The McDermott Bridge is the fourth bridge in this location over the Cold River. The bridge was reportedly constructed by Albert S. Granger of Westminster, Vermont, using virgin timber taken from nearby Fall Mountain. Granger’s father, Sanford Granger (1796–1882), purportedly patented his truss design in 1833. However, there is no record of a patent for a bridge design attributed to Sanford Granger. If it existed at all, his patent request is believed to have been destroyed in the fire in the patent office on December 15, 1836. The bridge is often referred to as a “Granger Bridge” in reference to the builder, not the truss design. The bridge is a Town lattice truss. The bridge was bypassed in 1961 and sat largely unattended until it was rehabilitated in 2008 by Daniels Construction, Inc. of Ascutney, Vermont. Funded by monies raised by the Langdon Covered Bridge Association, the McDermott Bridge project cost $131,257. The McDermott Bridge is listed on the National Register of Historic Places.[1]
