Crews begin construction by setting up the work-zone which takes 45 minutes to one hour. After traffic is safely shifted on one side of the bridge, a large vehicle carries a new pre-constructed segment onto the construction site. As two large cranes are put in position, crews spend about two hours saw-cutting a segment. The two cranes lift that cut segment out and place it on a flat bed truck to be carried off the bridge. The cranes then lower the new segment into place.
Crews secure segment and continue process with second segment.
The work zone is cleared by morning rush-hour. The bridge is 4,185 feet long. Crews will remove and replace a total of 230 segments, the majority of which are 88 feet long and weigh 120,000 lbs. Those segments are produced in a casting yard located at the WasteWater Treatment Plant off the Maury Street interchange. Each segment includes the concrete driving surface, steel girders and jersey walls.
