The Walton Bridge in Keene, New York was built in c. 1890. It was listed on the National Register of Historic Places in 1999. It was destroyed in the flooding caused by Tropical Storm Irene on August 29, 2011. History From the registration form for the National Register: The Walton Bridge was originally constructed c.1890 for the Western Plank Road Company in the hamlet of Black Brook, New York, in (Clinton County, NY) to cross a stream known as Black Brook. The bridge was part of a 14-mile toll road between Black Brook and Franklin controlled by the Western Plank Road Company, which was incorporated in 1850. The Walton Bridge was manufactured and erected by the Berlin Iron Bridge Company (BIBC) of East Berlin, Connecticut. The BIBC, which was formed in 1883, evolved from a series of iron manufacturing businesses (American Corrugated Iron Co., 1868; Metallic Corrugated Shingle Co., 1871; and Corrugated Metal Co., 1873) that made corrugated iron, fireproof shutters and doors and iron roof trusses. In the late 1870s, the Corrugated Metal Company bought the rights to William 0. Douglas's patented lenticular bridge truss design and entered into the bridge fabricating market. By 1883, most of its business was in bridge fabrication and its name was changed to reflect this. While Berlin Iron Bridge Company (BIBC) did manufacture bridges of other designs, it primarily built lenticular truss bridges. In all, about 1,000 lenticular truss bridges were fabricated by the BIBC between 1878 and the late 1890s and they were sold as far away as San Antonio, Texas. BIB grew to become the largest structural fabricator in New England and was acquired by the American Bridge Company in 1900. The East Berlin factories were eventually dismantled and moved to the new plant in Pennsylvania. In 1925, the bridge that crossed Black Brook was determined to be obsolete and replaced by a more substantial span. It was then moved to its present location in the Town of Keene to replace a bridge that had been washed away in a flood along with its abutments. A 1924 report of the Essex County Bridge Committee states that the original Walton Bridge "...was replaced by an old iron bridge obtained by the Town of Keene from its old site in the Town of Black Brook, being placed on the abutments newly built by the Bridge Committee".
