THE PROBLEM: The Delaware Department of Transportation is telling drivers from Maine to Florida to make plans to get around a section of an interstate that's closed because of columns that are tilting on a bridge in Wilmington.

HOW TO GET AROUND IT: The affected route, Interstate 495, parallels Interstate 95. So I-95 through downtown Wilmington is the main detour.

FROM NEW JERSEY, NEW YORK AND POINTS NORTH: Southbound traffic on I-495 is closed at the Pennsylvania state line, with traffic diverted onto I-95 southbound. Drivers traveling south from New York may want to stay on the New Jersey Turnpike, rather than getting on I-95, crossing into Delaware over the Delaware Memorial Bridge south of Wilmington and then getting back on I-95. Southbound port of Wilmington traffic is being directed to Interstate 295 east and then to Delaware 9 north to the port.

HEADING NORTH ALONG THE EAST COAST: Officials say I-495 is closed northbound at Terminal Avenue, which leads to the port of Wilmington. Drivers traveling north can stay on I-95 through Wilmington or take Interstate 295 into New Jersey and bypass northern Delaware. Local northbound traffic can stay on I-495 to Terminal Avenue.
