TIGHT SQUEEZE

The Newark, New Jersey, Route 21 Viaduct Replacement is a massive, $250 million highway improvement program being undertaken by the New Jersey Department of Transportation. Michael Baker Jr., Inc.'s Princeton, New Jersey, office is serving as the prime design consultant for the work, which includes replacing the obsolete Route 21 bridge, widening Interstate 78, and adding or improving several interchanges. The viaduct's alignment resulted in a series of tight curves with complex geometry. Since the bridge crosses Amtrak's busy Northeast Corridor, plus active Conrail lines, its spans had to be longer than usual and its piers demanded innovative design. Construction had to be completed during precisely planned two-hour windows to accommodate the 400 Amtrak, Contrail, and NJ Transit trains that pass under the bridge each day. Construction is underway and is expected to be completed by late 2003.
