West Bozeman Interchange Bridge Project

I-90 / North 7th Avenue Interchange Open
Seven Months Ahead of Schedule

Bozeman, MT—The bridge replacement portion of the West Bozeman Interchange work that began in March, 2013 is now complete and the entire bridge is open for motor traffic. The Montana Department of Transportation (MDT) project timeline estimated opening in September of this year, but innovative approaches applied by Dick Anderson Construction allowed the work to be done in record time and at considerable cost savings for the public. Finish work is scheduled for the spring, but will be minor compared to the 2013 construction.

Allan Frankl, Project Manager for Dick Anderson Construction expresses appreciation for the cooperation of Bozeman area residents and businesses during the construction. "Work of this magnitude in a metro area is always disruptive and noisy. We commend people for their patience while traffic patterns changed and equipment and crews were working in numerous locations," says Frankl.

Benefits of the North 7th Avenue bridge work include the development of four driving lanes and two left hand turn lanes onto the I-90 westbound on-ramp; five-foot shoulders that accommodate bicycle traffic; and five-foot sidewalks that will be ADA accessible. Other improvements will include new luminaires, traffic signing and signals.

The West Bozeman Interchange work and bridge retrofit projects at Bear Canyon, Fort Ellis, L-Street, and Valley Center Road have addressed structural vulnerabilities relative to earthquakes and improved traffic capacity and function.

Paul Cogley, local MDT Project Manager cited that perhaps the greatest achievement for a complex project of this scale is the outstanding safety record. "The contractors and the traveling public cooperated to get the project completed without any major incidents," says Cogley.

In addition to community cooperation and support, Dick Anderson Construction was assisted in reaching completion of the bridge work through the involvement of a number of subcontractors. These firms include Knife River Corporation; Poteet Construction, Inc.; H & H Earthworks, Inc.; Grizzly Steel, Inc.; High Mark Construction; Penhall Company; Montana Lines, Inc.; Becker Landscaping; and Olson Communications.
