Project Description

We provided engineering and design services associated with the Democrat Road (CR673 MilePost 4.41) over I-295 MP 16.42 Rehabilitation project, which involved the replacement of the deck slab of the existing bridge. The project involved replacing the deck slab with minimum environmental and community impacts. Other incidental work included replacement of the approach slabs at both ends of the bridge, isolated repairs of cracks and spalls in substructure elements, and replacement of guiderail/fencing/curbing. Work also included milling and overlay of the approach roadways.  Due to low traffic volume on this section of Democrat Road and the availability of feasible detours utilizing I-295, NJDOT accelerated the reconstruction by full closure of the bridge.  The existing single spans were made continuous for live load.

The existing bridge, built in 1953, was a two span simply supported, composite riveted plate steel stringer structure supported by concrete abutments and piers.  The bridge deck slab was severely deteriorated with many visible spalls and rated ‘Poor’ (4) in Structure Inventory & Appraisal condition rating.  The deck slab was deemed functionally obsolete and in need of replacement.

SJH was responsible for preparing a Design Exception Report, utility coordination, and providing a complete set of construction documents. This project received the 2014 Engineering Excellence - Distinguished Award from the American Council of Engineering Companies.
