tanker drove off the Christina River bridge and exploded, with the truck driver killed. The accident forced the closure of I-495 in order to repair the heat damage to the bridge structure. In 2000, through traffic from I-95 was detoured onto I-495 while I-95 was rebuilt between Wilmington and the Pennsylvania state line. On June 2, 2014, the bridge over the Christina River was closed after it was discovered that four support columns were tilting. I-495 was indefinitely closed to traffic between the DE 9A and 12th Street interchanges. Delaware Department of Transportation officials later announced plans to have the southbound side of the bridge reopened by Labor Day, with the northbound side to follow by late September. The southbound lanes reopened on July 31, a month earlier than expected, and the northbound lanes reopened on August 23. During the closure, traffic was detoured onto I-95, and several major roads in the Wilmington area experienced increased traffic congestion.
