Moretrench’s Rapid Response Capability Earns Delaware River Bridge Repair Contract

February 2, 2017

The Delaware River Bridge, which carries 42,000 vehicles daily between the New Jersey and Pennsylvania turnpikes, has been closed since January 20th when a significant crack in a truss member beneath the deck was discovered during final painting inspection. The bridge was immediately shut down, and Moretrench was one of several geotechnical contactors contacted the next day by the New Jersey Turnpike Authority to provide the micropile foundation systems proposed for support of eight temporary steel jacking towers that will stabilize the bridge during repairs.

“We demonstrated that we had the resources to do the work and were able to mobilize immediately,” said Project Manager Yaser Taheri, P.E.  “We were awarded the job on the 23rd and were on site the next day.”

The fast-track operation calls for six, high capacity micropiles installed at each jacking tower location to depths of between 120 and 140 feet.  The towers will tie directly into the foundation system. Moretrench has mobilized three drill rigs and five crews and has been working around the clock since Day 1.  “We are installing micropiles at several locations simultaneously,” said Taheri. “Despite difficult drilling through variable geology, we are comfortably within schedule.”
