Glacier National Park is accepting public comments on a proposal to conduct streambed maintenance and install riprap as needed to bridges and culverts along the Going-to-the-Sun Road.
Maintenance of bridges and culverts along the Sun Road occurs under the park’s road maintenance guidelines, which permit routine clearing of debris from within 10 feet upstream or downstream. Rehabilitation of several of the road’s historic bridges and extensive drainage work has also occurred as part of the road’s ongoing major rehabilitation project, but a number of bridges and culverts are located where flooding and potentially damaging sediment loads occur frequently, and additional stream work is required, according to the park.
The park is proposing to remove, or dredge, sediments as needed from stream channels at bridges and culverts along the Going-to-the-Sun Road beyond what already occurs. The proposal also includes placing riprap at the Logan Creek Bridge and other bridges and culverts along the road as needed to reduce sediment deposits caused by erosion.
Comments are due Jan. 3.
