Project Summary


Cast-in-Place Balanced Cantilever Main Span with Precast Segmental Approaches

This design/build Project included two twin elevated viaducts and river crossing bridges. River crossing is a segmental bridge structure built utilizing cast-in-place, balanced cantilever construction. Approaches were precast segmental using an overhead gantry to erect the spans in balanced cantilever. Each bridge carried traffic in opposite directions. The two cell box girder, of the river crossing, has a deck width of 68 feet and was cast using form travelers. Spans vary from 350ft to 685ft.

Project Cost: $200 Million

Client: Parsons Brinkerhoff Quade & Douglas Engineers
