A record-span, precast concrete segmental bridge--one designed for erection using a temporary pier and a 300-ft. erection truss--is being constructed instead as a balanced cantilever with the aid of a 36-ton counterweight. Use of the counterweight on the main spans frees the erection truss for use on the long, repetitious approach spans. T.L. James Associates is now completing the $32.2-million, 3-year contract to construct twin 7900-ft.-long structures to carry I-526 over the Wando River near Charleston, South Carolina. The 400-ft. center spans are a record for precast segmental concrete bridges. Details of the construction to date are provided in this article.
