Bonner Bridges Project

Environment Considerations

Environmental concerns will remain at the forefront during construction. Any instream will be done in accordance with state provisions to protect bull trout. The construction site is located within the Milltown Superfund site, where some soils contaminated with heavy metals have been previously capped in place. Contaminated riverbank soils removed during construction will be transported to the Missoula landfill, where they will be capped and contained.
