Project Summary

The Beaverkill Covered Bridge is a distinct regional variation of a Town Lattice Truss with fanlike radiating planks in the end panels. It is the best preserved surviving example of this type, all constructed by local builder John Davidson. The trusses follow an earlier version of the Town patent and include a single upper chord. Due to the length of the bridge and lack of a secondary upper chord, the bridge has exhibits racking and sweep throughout its length. The goal of this project was to rehabilitate the bridge and correct known deficiencies.

We performed a full NBIS bridge inspection and load rating as a subconsultant to a regional engineering firm. Deficiencies noted at the bearings and at mid-span of the downstream truss required temporary closure of the bridge while repairs were designed. As the bridge is a key route within the state park in which it is located, we prepared accelerated design drawings with construction completed by NYSDOT bridge maintenance personnel. The bridge was re-opened in time for the busy summer camping season. Hoyle, Tanner also designed the full rehabilitation of the covered bridge, which was completed in November 2016. The project received partial funding through the National Historic Covered Bridge Preservation Program.
