This view is of the roadway work at the east approach to the new Route 72 Manahawkin Bay Bridge. Rollers are used to compact the subgrade material, paving machines are used to place asphalt to the proper grade, and finall rollers pass over the asphalt again to provide a smooth and unyielding surface.

This view is of the West Thorofare deck surface facing the pedestrian walkway on the north side of the bridge. A crash-tested four-bar railing is placed between traffic lanes and the walkway to protect pedestrians from the rist of an errant vehicle. Similar separation barriers will be installed on each bridge crossing on the Route 72 Causeway that supports a sidewalk.

This view is of the tempoarary nest box on the new Route 72 Manahawkin Bay Bridge inhabited by its newest resident. A pair of Peregrine Falcons, which are listed as an endangered species, are happily taking full advantage of their new temporary nest box. Once construction of the entire corridor is complete, a permanent nest box will be installed on the rehabilitated existing Route 72 Manahawkin Bay Bridge, equipped with similar features to this nest box.

This view is of the outside face of the Mechanically Stabilized Earthen (MSE) retaining wall at the southeast approach of the new Route 72 Manahawkin Bay Bridge. Riprap stones are placed on the ground to protect the shallow foundations for the MSE walls in the event of a large storm surge. At this location, the average stone size is 8". At the westerly retaining wall, the average stone size is 21" and a steel sheetpile bulkhead is also provided to minimize the amount of fill in the bay.

This view is of a highway lighting fixture mounted on the traffic barrier on the south side of the new Route 72 Manahawkin Bay Bridge. The lights on the bridge and the adjacent Mechanically Stabilized Earthen (MSE) retaining walls make use of the light emitting diode (LED) technology. The LED lighting has a longer service life and should require less maintenance compared to standard high pressure sodium (HPS) lights. The string of pearls lighting that was previously on the old bridge will no longer be used to light the roadway, but a replication of the lights will be mounted on the outside face of the bridge parapet to provide an aesthetic viewpoint from shorelines.
