Steel highway bridges are constructed using a combination of pre-fabrication and on-site assembly techniques. The process typically involves designing the bridge, fabricating the steel components off-site, transporting them to the construction site, and then assembling them using cranes and other heavy machinery.
Steel highway bridges are constructed through a process that involves several key steps. First, the foundation for the bridge is prepared, typically by constructing piers or abutments. Then, steel girders or trusses are fabricated off-site and transported to the construction site. These girders are lifted into place using cranes or other heavy machinery. Once in place, they are bolted or welded together to form the bridge structure. Concrete or steel decks are then attached to the girders to create the driving surface. Finally, the bridge is inspected and tested for safety before being opened to traffic.
