Moving the 1918 Snyder Brook Bridge
NH State Parks
Brief history citing historical significance
Written by Will
Largely due to the influence of its in house engineer, Jonathon Parker Snow, the Boston & Maine Railroad continued to build wooden bridges longer than any other major railroad, building the the last of it and Snows typical Double Town Truss covered spans in 1916 (though an early example, it is typical in detail of the the hundreds which would follow - see the Contoocook RR Bridge) – For shorter spans, the B&M's choice was that of Boxed Pony Howe's, the Snyder Brook Bridge is the last surviving example.
The thirty mile Berlin Branch was built in the early 1890's by the Concord & Montreal Railroad, this line was leased shortly thereafter by the B&M, which quickly set about upgrading the bridges on the line in anticipation of the heavier rolling stock of the future. The Snyder Brook was one of at least three Boxed Pony Howe's built on the branch in the Summer of 1918 The B&M continued to run the line for ninety one years, it was then briefly leased by Guilford Transportation and continued to carry trains until the early 1990's before being abandoned. The railbed and the Snyder Brook bridge are now part of the Presidential Range Rail Trail.
