Construction & Assembly

Steel box girders are typically fabricated off-site and lifted into position using cranes, with sections connected by bolting or welding. The modular design enables incremental launching methods using gantry cranes to place new segments onto completed portions until the superstructure is finished.

Bridge Components

The modular system consists of three main parts: floor transoms (19-foot width), stringers (10-foot length), and side panels (10-foot-long, 5-foot-high cross-braced rectangles). Each panel weighs 570 pounds and can be handled by six workers.
