The Weirton-Steubenville (Veterans Memorial) Bridge is a 1,965-ft-long cable-stayed structure spanning the Ohio River. The bridge consists of two cable-stayed spans of 820 ft. and 688 ft., and four approach spans. The superstructure system is composed of steel girders, floor beams, stringers, and a composite concrete deck. It is suspended by cables arranged in a fan-like pattern, anchored at 60 ft. intervals along the deck. The contractor, S.J.Groves and Sons Company, engaged T.Y. Lin International (TYLI) to perform erection analysis for this bridge.

Kwong Cheng, current OPAC Principal, served as Project Manager and Lead Engineer while at TYLI and established the segmental erection sequence for the bridge superstructure, including segment-by-segment erection of form travelers, placement of concrete, stressing of stay cables, and moving of formwork. Based on this sequence, he developed a complete stage-by-stage erection sequence computer program, to track each construction stage. This modeling provided camber charts and stay cables stressing specifications for use by the contractor.

Francis Drouillard, current OPAC Principal, served as Design Engineer while at TYLI and prepared construction details.
