A variety of steel-frame commercial bridges along typical multiple-use trails.
by Stuart Macdonald, Trail Consultant, American Trails
Most of these bridges are standard designs from several manufacturers, but with some individualization in abutments and approaches. These bridges are built off site and installed on shared-use pathways used by bicyclists and pedestrians. Some have very long spans, and others have a very pronounced arched profile. The material is typically a “weathering steel” which forms a tough coat of rusty brown corrosion and never needs painting.
