Lamar River Bridge (existing)

Lamar River Bridge

Yellowstone National Park » Lamar River Bridge » Document List

The National Park Service is planning to replace the Lamar River Bridge east of Tower on the Northeast Entrance Road. The Lamar River Bridge is located about five miles east of Tower Junction. In accordance with the National Environmental Policy Act, the park prepared an environmental assessment (EA) which looked at two alternatives for the replacement of the bridge, which was built in 1939.

While a recent Federal Highway Administration report lists the bridge in fair to poor structural condition, there are no safety issues which should be of concern to travelers. Over –size and over- weight vehicles are strictly prohibited from traveling across the bridge. The National Park Service has denied travel over the bridge by construction or logging trucks involved in work in and around Cooke City, Silver Gate, and the Beartooth Highway.

The NPS recently signed an Finding of No Signifiant Impact (FONSI) for this project. A copy of the FONSI and EA can be found by clicking the Document List link at the left on this (PEPC) website at http://parkplanning.nps.gov. The FONSI is also available by writing:
