A worker inspects the underside of the Interstate 495 bridge over the Christina River near Wilmington, Del., Tuesday, June 3, 2014, after it was closed due to the discovery of four tilting support columns. The closure created heavier-than-normal traffic conditions for motorists on Interstate 95, a major East Coast artery. The bridge normally carries about 90,000 vehicles a day.
