Streambed Maintenance and Riprap Protection at Bridges and Culverts along the Going-to-the-Sun Road
Planning and Environmental Compliance
Glacier National Park
A number of culverts and bridges along Glacier National Park's Going-to-the-Sun Road, including the historic Logan Creek Bridge, are located where high water and flooding occur frequently. Sediment and debris from flooding can completely clog bridge spans and culverts and, in some cases, result in unstable channel alignments that are prone to flooding. To maintain stream flow, allow for improved flood water conveyance, and protect historic bridges and culvert headwalls, the park is proposing to remove, or dredge, sediments and place riprap as needed at bridges and culverts along the GTSR.
