McMahon was contracted for the redecking/rehabilitation of Bridge NB-528 located at the Mahoning Valley Interchange in Franklin Township, Carbon County. McMahon prepared the final plans and contract documents for the redecking/rehabilitation which were in accordance with the current version of the Pennsylvania Turnpike Commission’s Design Consistency Guidelines. The work associated with this project includes replacing the entire deck, parapets, deck joints, median barriers, bearings, backwall, and electrical conduit located within the barrier. In addition, slabs at each approach will be installed, the superstructure will be cleaned and painted, select cross bracing members may need replaced, abutment stems will be repaired and all concrete surfaces will be coated with an anti-graffiti coating.
