MISSOULA — The Montana Department of Transportation (MDT) and BNSF Railway are moving forward with a pier removal and bridge mitigation project for the Blackfoot River near Bonner.
The plan involves installing grout-filled bags and riprap to stabilize the bridge without affecting aquatic habitats, costing an estimated $9 million.
Construction will begin this summer, with some recreational and access closures expected, particularly during significant in-river work in 2026.
