Custer Avenue Interchange
On June 1, 2012, Montana Governor Brian Schweitzer, United States Senator Max Baucus, and several other local officials dedicated the new Custer Interchange in Helena, Montana. After eight years of environmental processing, planning, design and construction, this $52 million project is now a reality. Well-received by local businesses and the general public, the Custer Interchange improvements have solved long-standing drainage issues, redefined the area’s traffic mobility and improved one of the city of Helena’s fastest growing commercial areas.
Morrison-Maierle and the Montana Department of Transportation began the design process for the Custer Interchange project in 2004. Projected to be complex and challenging, Morrison-Maierle and the Department immediately began planning for the challenges associated with reconstructing one of the area’s significant commuter roads in a congested utility corridor. Development of a comprehensive traffic management plan, early acquisition of right-of-way, utility relocation planning and oversight, and real-time traffic signal control operations in coordination with the contractor all contributed to minimizing disruptions to the traveling public.
