Rarus Silverbow Creek Structure Improvements
The Rarus Silverbow Creek Structures project will replace and upgrade four bridges on Interstate 15/90 west of Butte (between the Montana Street and City Center Exits). Two bridges will be replaced each construction season over the next two years. These structures require replacement to improve safety of the roadway including wider bridges and shoulders.
The project is scheduled to start April of 2018 and be complete in Summer of 2020.
Impacts to the Public
The public can expect reduced speeds, single lane traffic, and should plan for extra travel time in the area. The north/east bound I-15 City Center Exit 124 will be closed while bridge replacement work is underway. I-15/90 traffic will be directed to use Exit 126 Montana Street. There is also a 12ft width restriction in place until the fall of 2018.
