Henry Woods Bridge Replacement

Bushkill Township, Northampton County, Pennsylvania

McMahon prepared design documents for the replacement of Henry Woods Bridge crossing Bushkill Creek in PennDOT District 5-0. This existing pony truss, surrounded by state park lands and the Jacobsburg Historical District, was damaged during flooding. The project involved Section 4(f), 6(f) and project “70” funds and was essential that a “No Adverse Effect” finding was issued. McMahon worked with PennDOT, FHWA, DCNR, and the Historical Society to minimize required right-of-way and utilized aesthetic bridge treatments to aid in the No Adverse Effect finding. Utilizing TEA-LU’s de minimus criteria, we receive environmental clearance in a short 18 months.


Bridge Rehabilitation at Mahoning Valley Interchange

Franklin Township, Carbon County, PA

McMahon was contracted for the redecking/rehabilitation of Bridge NB-528 located at the Mahoning Valley Interchange in Franklin Township. 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.


Florida Region

Park South Residential Community Bridge Inspection

Lauderhill, Broward County, Florida

McMahon performed a bridge inspection of a three-span pre-cast double-tee beam pedestrian bridge. Field inspection was accomplished by a two-man team which included inspection of the super structure, substructure and soundings throughout the canal adjacent to the structure. The field inspection was performed in accordance with the National Bridge Inspection Standards. The report summarized the conditions of the components including the railing, approach slab, deck, superstructure and substructure, as well as scour conditions from the sounding results. The report provided recommendations for needed improvements, on a priority basis, and associated costs.
