Lewis River Bridge Replacement Next Year

Written by on February 14, 2019

Construction work is cleared to begin in spring of 2020 on a bridge over the Lewis River in the southern part of Yellowstone National Park.

At the end of last year, a Finding of No Significant Impact was declared on an environmental assessment for a project to replace the Lewis River Bridge. The bridge is located south of the Lewis Lake Campground on the South Entrance Road.

The replacement will be built on a new alignment directly east of the existing bridge. Parking and pedestrian areas located north and south of the existing bridge will be redesigned and reconstructed.

The project will shift the South Entrance Road several hundred feet to line up with the new bridge. Traffic will continue on the existing bridge while the new one is under construction.

Depending upon funding, roadwork could begin as early as spring 2020 and last for two consecutive years followed by the spring of a third year. The Lewis River Falls Overlook Trail and parking areas would be closed during construction.
