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.

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.
