The approaches and main span of the James River (Varina-Enon) Bridge consist of two parallel box girders. The main span is a 600-ft-long cable-stayed bridge. The construction was based on precast segments that are match-cast on the ground. An erection truss was used for the approaches, and cantilever construction was used for the main span. The main span's stays are located in a single plane between the two box girder sections. The contractor engaged T.Y. Lin International (TYLI) to provide engineering support services for the construction of this bridge.

• Kwong Cheng, current OPAC Principal, served as Supervising Engineer while at TYLI, and worked closely with the contractor throughout the construction phase. Work performed include the development of a detailed stage-by-stage erection procedure, casting curves for the main span, and redesign portions of the structure due to changes in the erection loads. The analysis of the segmental erection sequence for the bridge superstructure, including segment-by-segment erection of steelwork, placement of concrete, stressing of cables, and moving of formwork was done using compete time-dependent erection sequence computer model in the SFRAME/S3D computer program. The results of the analysis were used to develop camber charts and cable stressing specifications for use by the contractor.
