NJTurnpike, Interchange 145- Contract P300.433 Essex County, New Jersey

The contract limits stretch from Garden State Parkway MP 144 in Irvington to MP 152 in Nutley traversing Newark and Bloomfield with the bulk of the work taking place in East Orange.

This project is anchored by the staged complete replacement of Central Avenue in East Orange over the Garden State Parkway. The existing bridge is to be replaced with a new structure with the abutments pushed further back than the current configuration and eliminating the central pier this will allow for the widening of the Parkway mainline below. The new structure will carry Central Avenue traffic over the Parkway and major utilities such as water, electric, gas and communications. These utility improvements extend past the bridge limits into the adjacent neighborhoods.

Additional work around Central Ave in East Orange includes the construction of a protective structure for an existing 42inch gas main with very little cover. This protection consists of a concrete top slab supported by micro piles and vertical steel plate for lateral protection. Also around Central Ave, retaining walls are being constructed, and existing ones are being under pinned and/or having their parapets replaced. New overhead signs structures supported on drilled shafts are slated to be installed in this area too. Neighboring intersections will have traffic signal and lighting improvements. The Oraton Parkways flanking the Garden State Parkway will be reconstructed full depth and/or milled and paved as required in various locations. The interchange 145 plaza will have the northbound exit toll demolished.

At the northern limits, Montgomery Avenue and East Passaic Avenue over the Parkway we will replace the existing deck slabs and also a few bearings. South of Central Ave in Newark two bridges where the Parkway passes over local roads will have the medians and parapets demolished and replaced along with the addition of structural steel diaphragms.

At the Southern Limit in Irvington, the Parkway passes under a bus terminal which has recently been reconstructed above. Our work at this location includes extensive spall repair on the abutment faces and per cap, with bearing replacement. Along with this work all existing lighting which is mounted on the abutment walls must will be replaced.
