A LOOK AT WHAT SOME STATES ARE DOING. NJDOT REPAIRS CRITICAL STORM-DAMAGED STATE BRIDGE IN RECORD TIME

In New Jersey, a heavily travelled highway bridge was closed when 2.5 inches of water above the deck washed out the abutment supporting the north end of the bridge. During the emergency work, the entire deck was lifted for repair, abutments were stabilized and piles were driven below the deck. The work was completed months earlier than anticipated. This note briefly describes the details of the operation in which eight steel I-beams were placed across the spans with end suupports on the approaches. Two cross beams underneath the bridge were suspended from the 8 beams on the top. Four 200-ton hydraulic jacks were set on top of the I-beams with 12 threaded rods connecting the upper and lower I-beams.
