Bayonne Bridge Project Presents Huge Construction Challenge

April 30, 2015

The $1 billion Bayonne Bridge Navigational Clearance Program in New Jersey is “the most complex undertaking of its type in the world,” reports the Hudson Reporter.

Once completed, the bridge’s roadway will be raised nearly 65 feet to allow super-sized vessels to pass underneath

The project is expected to create 2,500 construction jobs and $380 million in wages.

Instead of a costly (approximately $2.4 million) and time consuming process of building an entirely new bridge, the New Jersey Port Authority came up with a plan to reconstruct the bridge.

The project requires raising the roadway to 215 feet, and never fully closing the bridge down throughout the construction process.

This process means bringing 100-ton precast lengths of roadway by barge from Virginia, pushing them across the bridge by a horizontal crane and then lowering them into place for construction.
