Advantage Steel and Construction successfully completed the erection of a seven span steel girder bridge over the Monongahela River in two phases. Installation and removal of temporary falsework towers and tie-down systems were necessary for stability during erection in both phases. Critical lifts included 10’ deep girders in excess of 200,000 pounds. Conventional erection was performed on land and in water for both phases of the erection. After completion of both phases, cross frames were installed between the two phases to tie the structures together.
