Our Route 9 project over the Raritan River was the Company's first Design-Build project. Construction commenced in October 1999. The project involved the design and construction of a 4,400 foot long, 60 foot wide bridge spanning the Raritan River and adjacent land from Sayreville to Woodbridge, New Jersey. The bridge was constructed in tight quarters between two existing bridge structures, the existing Route 9 bridge to the east and the Garden State Parkway Driscoll Bridge to the west.

The four lane superstructure is 100 feet above the river's surface at its highest point, and is comprised of five continuous span units, four of which are made up of post tensioned, spliced, concrete girders with a structural concrete deck and the center unit, over the water, is a continuous steel structure with a structural concrete deck.

The substructure is comprised of twenty-five piers and two abutments founded on a combination of friction and bearing piles. The abutment was poured in place with special architectural features. Abutment retaining walls are precast T-Wall construction. To facilitate construction of the water piers, eleven temporary steel cofferdams were constructed. Pier caps consist of a mix of conventional and post tensioned integral pier caps supported by twin concrete columns. The project involved the reuse of excavated soils in accordance with an approved soil reuse plan and the implementation of a project Health and Safety Plan.

Reconstruction and rephasing of the bridge approaches was also included in this contract.

This project was completed on time and within budget
