Specimen Creek Trail Bridge Replacement FWP-DN-Fisheries-R3-25-008

Apr 8, 2025 10:02 AM

The existing footbridge across Specimen Creek, which was damaged by the 2022 flood, will be removed by helicopter. The new bridge will be a prefabricated steel structure 44-feet long and 8-feet wide. The bridge will be supported by sills located beyond the streambanks. In accordance with the Custer-Gallatin Forest Plan, the bottom of the bridge stringer will be at least 3 feet above the 100-year water surface elevation. Such conditions will ensure the bridge has little to no effect on stream morphology, water quality, or aquatic habitat, which will significantly improve conditions in and around the stream. Disturbed areas will be rehabilitated by recontouring and reseeding with an appropriate native seed. The work will be completed by the US Forest Service between May 15, 2025, and October 31, 2025.
