Washington County Department of Public Works, NY County Route 113 (Clark Mills) over the Batten Kill

To replace this historic structure, the State Historic Preservation Office required extensive coordination, a Historical American Engineering Record, a Finding Document, and a Memorandum of Understanding. The presence of precontact artifacts found during the Phase 1a/b study required tribal coordination and special conditions to be designed and implemented during construction. Various New York State Department of Environmental Conservation and Army Corps of Engineers permits were required due to the instream work and the waterbody’s use as a fish (walleye) spawning area.

The new bridge consists of new concrete abutments, two cast-in-place concrete piers with 11-ft travel lanes, and five-foot-wide shoulders to accommodate bicycle traffic. The superstructure also includes a stone curb, a five-foot-wide sidewalk on one side of the road, and a steel bridge railing. An architectural treatment-stained custom rock form liner was applied to exposed vertical surfaces to replicate the old bridge. Approaches were realigned, including new traffic signs, pavement markings for the roadway, and two high-visibility pedestrian crossings.

GPI provided preliminary and final design services (Design Phases I-IV), including topographic survey and mapping, environmental studies, preparation of a design report and a bridge conceptual structure plan, final bridge and highway design plans and specifications, preparation of construction bid documents, and construction support and inspection services.
