The new bridges were designed as single-span structures with no intermediate piers to remove unnatural waterway obstructions. The old structures included three spans with two piers constructed within the waterway.
Removing the piers creates a more natural stream flow, allows debris to pass more freely, and improves fish habitat. The North Fork of the Blackfoot River supports the fluvial bull trout (listed as a Threatened Species under Endangered Species Act). The design from this new project supports the client and community by promoting native species and at the same time, provides quality access to public lands.
With these new bridges, the Forest Service and backcountry users now have access to the Scapegoat Wilderness with for years to come.
