Abstrakt:

Construction of the 27.5 meter (m) suspension pedestrian bridge over Rattlesnake Creek near Missoula, Montana provides an aesthetic and innovative link in the city’s trail system. Engineers reviewed historic U.S. Forest Service trail suspension-bridge construction, relying on proven technology while incorporating small diameter roundwood (smallwood) salvaged from bug-killed lodgepole pine, along with other sustainable design materials. Lattice stiffening trusses, floorbeams and braces, constructed from small diameter roundwood, qualified the bridge for grants including

U.S. Forest Service funds. They also provide an aesthetically pleasing context sensitive tie with the forested environment. Other sustainable materials used in the bridge construction include 100 mm x 300 mm composite decking from sawdust and recycled plastic, and an 18 mm thick rubber mat wearing surface from recycled tires.
