Old Blenheim Bridge Replacement

North Blenheim, New York

Client: Greenman-Pedersen, Inc.


  • Preliminary Design

Project Summary

The Old Blenheim Bridge was a single-span, double-barrel Long Truss wooden covered bridge built in 1855 and located in North Blenheim, New York. The bridge was destroyed by flooding associated with Tropical Storm Irene in 2011. The bridge owner, Schoharie County New York, selected the team of Greenman-Pedersen, Inc. (Project Lead) and Hoyle, Tanner & Associates, Inc. (timber covered bridge designer) to design a replica of the former National Historic Landmark bridge. The new bridge retained the overall structure/appearance of the original while being founded on new abutments above the 500-year flood elevation.

The 228’ long replacement bridge, constructed in 2018, is one of the longest single-span covered bridges in the world. The bridge replaces a key piece of the Town’s history and culture which was previously identified as a National Historic Landmark. In addition, it demonstrates the significant role that engineering plays in our infrastructure.
