Manahawkin Bay Bridge
Posted May 27, 2014, by Doug (Doug4sails [at] gmail [dot] com)

This bridge is also known as the Dorland J. Henderson Memorial Bridge, so named for the inventor of the hand-rail lighting system installed on it.

The bridge has serious structural problems and is being replaced with a parallel span to its immediate south. After replacement, the existing span will be completely rehabilitated from the piers up, and will carry two westbound lanes with shoulders.

The temporary work-causeway is completed and work has begun on the foundations for the new piers. Total project completion will be in 2020.

Attached are some photos shot May 26th, 2014 showing the bridge and work in progress.
