U.S. Bridge Truss and Beam Bridges permit more economical design solutions than alternative structures. Due to the high strength-to-weight ratio of fabricated structural steel, many of our bridges utilize existing abutments. Longer span lengths eliminate expensive piers that can obstruct waterways. Adaptable to local conditions, U.S. Bridges accommodate skewed alignments, roadway widths from one to three lanes, local utilities and sidewalks. Flooring options include timber, concrete, open grid and our own corrugated steel planks with an asphalt wearing surface. U.S. Bridges can be designed for AASHTO HS-20, HS-25 or heavier loadings such as those encountered in the mining industry.
More options mean
we get it done right.
