A grillage system was installed at each pier to support full length girders underneath the existing bridge deck. Phase 2 involved the erection of new girders for traffic lanes on the north and south sides of the existing bridge. After demolition if the remaining existing structure, NRE mobilized to erect the balance of the new structure between the previously erected north and south structures. |
