Rt. 22 Deck Replacement

SJH was the prime consultant fully responsible for the project to replace the bridge deck of Route 22 West Bound (WB) over the ramp to Route 22 East Bound (EB). The Final Design of this project addressed the deficient deck slab and approach slabs with minimal environmental and community impacts to the densely occupied area adjacent to the bridge.

The team conducted an in-depth inspection of the structure before beginning design and prepared repair details based on additional findings beyond the bridge inspection report. SJH designed a cast-in-place construction solution for the bridge deck replacement with a two-stage construction scheme. New shear stud connectors were provided, and the superstructure steel was designed to comply with the current AASHTO LRFD HL-93 live loads. The bridge’s sixty-seven (67) degree skew required SJH’s design to accommodate additional reinforcement to control cracking.

Other incidental work included the replacement of deteriorated end diaphragms at the abutments, isolated repairs of cracks and spalls in substructure elements, replacement of guiderail, fencing, and curbing, limited milling and overlay of the approach roadways, replacement of existing JCP&L light standards with NJDOT standard light standards, and the installation of a CCTV pole and other ITS components.

SJH provided construction support services for the $2.4M project.
