Madison Valley Bridges

MDT & Madison County, MT

Project Highlights

Famous as a fly-fishing destination and for its old-west charm, Montana’s spectacular Madison River Valley is flanked by mountain ranges and offers scenic beauty that is arguably unparalleled. Much of the area’s natural wonders are accessed by crossing Varney and Blaine Spring Creek Bridges, built in the late 1800’s. Both single-lane overhead truss structures were deemed functionally obsolete and given load restrictions of 3 tons. Great West supported Madison County and Montana Department of Transportation to complete the project development and design. Based on the public input and discussions with project partners, new weathering steel through-truss superstructures were selected as the preferred replacement alternatives. Although more expensive than traditional concrete or steel girder bridges, these structures captured some of the uniqueness of the existing trusses.
