route 72 manahawkin bay bridges project graphic


December 2015

(click on thumbnail photos to enlarge in bottom window)

This view is of the overall progress at the easterly approach to the new Manahawkin Bay Bridge. The precast concrete parapet has been erected and the reinforcement extensions for the anchor slab can be seen. Drainage inlets and pipes have also been installed and the soil has been compacted to support the roadway. The retaining wall shown is over 700 feet long and its maximum height if about 27 feet near the bridge.

This view from near the east abutment looking west provides a comparison of the new concrete beam bridge on the left and the existing steel girder bridge on the right. When Route 72 traffic is shifted to the new bridge and the superstructure is replaced on the existing bridge, new steel girders will be installed and painted to match the color of the concrete beams.

This view is of a finished section of the concrete parapet taken from the deck surface of the new Manahawkin Bay Bridge. All concrete deck sections have been poured and the parapet has been completed indicating the structure is nearing completion. Installation of highway lighting, aesthetic lighting and travel line striping are still pending.

This view is of the erected precast concrete facing panels for the Mechanically Stabilized Earth (MSE) retaining wall on the approach of the new Manahawkin Bay Bridge. The traffic parapet is being set on top of the wall using a small crane. The traffic parapet itself is precast concrete with reinforcement steel protruding from its base to facilitate a connection to a field placed concrete slab that anchors and stabilizes the parapet.

This view is of the temporary construction trestle that has been nearly completely removed. Several steel pipe pile foundations can be seen extending out of the water. Most of the these elements have been cut three feel beneath the mudline and disposed of off-site to prevent interference with marine traffic. This is part of the effort needed to clean the project site and restore the adjacent areas to their original conditions.
