Lamar River Bridge

Selected as a Winner in 2014 IBC Photo Contest

The New Lamar River Bridge in Yellowstone National Park was selected as one of the winners of the 2014 International Bridge Conference Photographic Contest — Bridges of the U.S. Federal Lands. The bridge is a three-span 420 foot long, haunched steel plate girder. Due to high seismic activity and active faults within 50 miles of the project area (the park sits atop a massive underground volcano) seismic vulnerability had to be taken into account for the replacement structure. One of the specific goals of this project was to build a structure to withstand the environment with architectural features that matched existing structures in the park while still blending into the natural environment.

Lamar River Bridge is located along Northeast Entrance Road in the Yellowstone National Park of Wyoming. It was also recognized in PE Magazine, Special International Bridge Conference Edition, and was also featured in the April 2014 issue of Modern Steel Construction magazine.
