Those bridges are the Commodore Barry, the Walt Whitman, the Ben Franklin and the Betsy Ross.
Also, the DRPA said the Commodore Barry Bridge will be closed to all traffic when sustained winds (not just gusts) reach 50 m.p.h.
Earlier Monday, the Pennsylvania National Guard activated 750 soldiers and expects to have a total of 1,600 placed on active duty to deal with damage caused by Hurricane Sandy.
Guard spokesman Staff Sgt. Matthew Jones says 50 guardsmen had already been on duty since Friday and 800 more based in Pittsburgh and Scranton expect to be activated by noon Monday.
Forecasters predict winds up to 75 mph and as much as 10 inches of rain to hit parts of Pennsylvania as Sandy slams into the mid-Atlantic.
State government is closed for the day and residents are being urged to stay home. All flights out of Philadelphia International Airport are canceled Monday and mass transit is shut down.
The Red Cross is opening shelters across southeastern and central Pennsylvania for residents fleeing their homes.

"This is not a typical storm," Gov. Tom Corbett said Sunday. "It could very well be historic in scope and in nature and in magnitude because of the widespread anticipated power outages, flooding and potential major wind damage to the commonwealth."
President Barack Obama early Monday signed an emergency declaration for Pennsylvania that will allow state officials to request federal funding and other storm assistance.
Corbett and Philadelphia Mayor Michael Nutter declared states of emergencies. State office buildings in Philadelphia, city offices and Philadelphia schools were scheduled to be closed Monday.
The storm was expected to result from Hurricane Sandy coming ashore late Monday or early Tuesday, most likely in New Jersey, and colliding with a wintry storm moving in from the west and cold air streaming down from the Arctic. Forecasters warned that the resulting megastorm could wreak havoc over 800 miles from the East Coast to the Great Lakes.
