Morrison-Maierle’s Deep Creek Canyon Weekend Bridges Replacement project was recently featured in ASPIRE, The Concrete Bridge Magazine.

One of Morrison-Maierle’s recent transportation projects was recently featured in ASPIRE, The Concrete Bridge Magazine. Co-authored by Jim Scoles of Morrison-Maierle and Kent Barnes of the Montana Department of Transportation, the article profiles the design of U.S. Highway 12 bridges at milesposts 17.3, 19.6 and 19.8. Read the article here.

The Lewis & Clark Highway – also known as U.S. Highway 12 – runs along the narrow floor of Deep Creek Canyon. The 24-ft-wide, two-lane highway between Townsend and White Sulphur Springs, Montana, was constructed in the 1930s with timber bridges at eight locations where the creek and the highway intersect. High flows during spring runoff in 2011 resulted in significant scour of the bridges and severe erosion of the highway embankment. The flooding required emergency response to prevent structural loss and ultimately triggered a project to replace these three bridges over three weekends in this rural area of southwestern Montana.

This project has received several statewide and regional awards, most recently a regional award in the 2015 America’s Transportation Awards competition in the “Best Use of Innovation, Small” category from the American Association of State Highway and Transportation Officials (AASHTO). The award was presented to Montana Department of Transportation Director Mike Tooley at the WASHTO meeting in Boise, Idaho, on July 22.
