The final beam is being lifted into place. All 102 beams required for the new bridge were set in only two months. This view is from the westerly approach with the reinforcement steel for the future bridge abutment in the foreground. Legs for the diagonal steel diaphragm bracings (on left) are attached prior to placing the beams for quick installation. Once the beam is in place, the crew works to attach the free end of the steel to the adjacent beam to increase stability.

This aerial view of the New Manahawkin Bay Bridge shows the progress with the west end of the bridge on the left. All 102 beams have been installed and can be seen along with the completed pier columns, bridge abutments and the temporary construction platform. The galvanized steel deck forms are being installed and can be seen on top of the beams starting from the east end and extending several spans west of the navigation channel. The galvanized reinforcement steel can be seen in the first span on the east end.

This aerial view is of the active portions of Route 72 Manahawkin Bay Bridges Project. All three bridge crossings currently under construction can be seen with the New Manahawkin Bay Bridge at the top (west end of project), the West Thorofare Bridge and the East Thorofare Bridge at the bottom. The environmental mitigation site on Cedar Bonnet Island (middle, left) will be used to mitigate for impacts to coastal resources, will improve habitat quality on Cedar Bonnet Island and improve recreation opportunties for residents and visitors to Long Beach Island.

This view is of the East Thorofare Bridge, which is the last of three bridges prior to Long Beach Island from the mainland. The trestles bridges are undergoing some minor widening at the deck level, deck resurfacing and deck joint replacement among other rehabilitation items. The southerly deck widening is formed and portions of the existing deck reinforcement can be seen extending into the work zone. The existing steel is exposed, protected and cleaned so the new deck concrete for the widening will have a positive connection to the remainder of the structure.

This view is of the work being performed on the West Thorofare Bridge (one of the three trestle bridges along the Route 72 Causeway), which is directly west of the East Thorofare Bridge. The West Thorofare Bridge work has progressed further than the East Thorofare Bridge at this time. The epoxy-coated reinforcement steel for the new concrete deck is being placed. The work on the trestle bridge is performed in stages so that traffic is not disrupted. The temporary construction barrier seen is used to protect the crew from live traffic.

The construction of the subsurface gravel wetland located at the intersection of Route 70 and Burnt Tavern Road continues. This wetland is designed to improve the health of the Barnegat Bay by reducing the amount of total suspended solids and nitrogen being deposited into the Bay. Two wetlands were constructed along Route 70 to meet the stormwater management requirements for the Route 72 Manahawkin Bay Bridges Project.
