CAREFUL PLANNING SPEEDS BRIDGE REPLACEMENT

In just 35 working days, Somerset County, New Jersey, replaced a 414-foot bridge spanning the Raritan River between the communities of Bound Brook and South Bound Brook. To meet this fast-track schedule, County Bridge Engineer Richard Strizki specified materials and procedures that made it possible to prefabricate large sections before the original bridge was closed. The decision to reuse the 110-year-old stone piers and abutments saved further time and money. Because the bridge had to be open to traffic as soon as possible, Strizki chose open-grid steel decking. Large sections of the open-grid decking were welded to the stringers before the bridge was closed. Six steel box girders were assembled and shipped to the site ready for placement. The old pier and abutment caps were removed, and new caps were poured. The wing-walls also required reworking. Once the box girders and floor beams were placed on the piers, erection of the decking proceeded rapidly. The resulting bridge consists of two 13-foot lanes for a clear roadway of 26 feet.
