New Jersey has to spend nearly $13.6 billion to bring its 6,447 bridges into good repair, according to a report made to the governor today by the state Department of Transportation. The $13.58 billion repair bill includes $8 billion needed over the next decade for bridges that fall under the state's jurisdiction, $1.5 billion for those owned by counties and municipalities, and $3.8 billion for bridges on the New Jersey Turnpike, Garden State Parkway and other toll roads. "All of our bridges are safe today, but our bridges are very old," Gov. Jon Corzine said this afternoon during a press conference in Jersey City. He was joined by DOT officials at a construction site near the approach to the Holland Tunnel at the Route 139 viaduct, which is undergoing $74 million in repairs. The report includes an assessment of the state's bridge conditions, as well as current repair and replacement projects. Corzine asked for the study after the deadly collapse of a Minneapolis highway bridge in August. "Maintaining the structural integrity of New Jersey's bridges is critical to our safety, quality of life and economic vitality," DOT Commissioner Kris Kolluri said in a statement. "The Final Bridge Report and Capital Investment Analysis provides a blueprint to improve infrastructure investment planning in order to ensure the continued safety of our bridges."
