Lewis River Bridge Replacement

Yellowstone National Park » Lewis River Bridge Replacement » Document List

The National Park Service is in the process of developing a plan to consider replacing the existing 273-feet long Lewis River Bridge in Yellowstone National Park. The bridge is located 9.8 miles north of south entrance gate. The project is needed to address widespread deterioration associated with this bridge built in 1960. The plan would also consider reconfiguring the adjacent Lewis Falls parking area to reduce safety hazards to visitors from its close proximity to the road and limited sight distance issues.

An Environmental Assessment will be prepared in compliance with the National Environmental Policy Act and Section 106 of the National Historic Preservation Act to provide the decision-making framework to evaluate a range of alternatives to meet project objectives and evaluate potential issues and impacts to park resources and values.
