PROJECT OVERVIEW

This $3.2 million contract with New Jersey Department of Transportation required the replacement of a 60-year-old bridge carrying vehicular traffic over the 40 ft. wide Raccoon Creek in the heart of downtown Mullica Hill, NJ. Employing Accelerated Bridge Construction (ABC) methods, a total bridge reconstruction was successfully performed during a 14-day road closure. Project scope included a full road closure to enable the demolition and reconstruction of the new precast bridge structure. The new bridge was comprised of eight precast abutment units, six pre-stressed concrete NEXT beams, and eight precast approach slabs. The precast closure pours was comprised of 25 cubic yards of UHPC, and 10 cubic yards of high performance epoxy grout. The project also required a custom engineered demolition debris shield, a complex cofferdam and flow diversion system, and a custom-designed/fabricated hoisting frame for erecting the 80,000 lb. precast pieces beneath overhead utilities. The bridge deck overlay required the use of a Bituminous bridge deck waterproofing system. All under tight timelines to meet critical project deadlines and milestones, the work was completed without incident and re-opened to traffic 31 hours ahead of schedule. The project also included the reconstruction of the stream bed using Articulated Concrete Block Matting for scour protection along with a comprehensive landscaping package for further beautification.
