D.C.-registered cars are, on occasion, driven beyond the Beltway. This one is shown heading northbound on I-95 from Delaware into New Jersey on the Delaware Memorial Bridge in early May 2007.
The Delaware Memorial Bridge is the longest twin suspension bridge in the world. The two separate bridges, which appear identical (although there are differences), together have carried more than 1.25 billion vehicles over the Delaware River between New Castle, Del., and Pennsville, N.J. since they opened.
The original span, which did not have a twin at first but now carries only northbound vehicles, was opened to traffic on August 15, 1951. Within four years about 8 million vehicles were making the crossing annually, almost twice the original projection. Talks soon began about constructing a second span, and it was opened in 1968. Three days later the original span was closed for a major overhaul, with the new southbound span accommodating two-way traffic. The refurbished northbound span opened three days before the end of 1969, and since then the two bridges combined have accommodated four lanes of traffic in each direction. On an average day about 80,000 vehicles transit the Delaware Memorial Bridge.
