If you're planning on driving to Lower Manhattan this weekend for the tenth anniversary of 9/11, don't. Or to use the language of the Metropolitan Transportation Authority: "Motorists are strongly cautioned to avoid driving in the area." Drivers will encounter tunnel closures, frozen zones and blocked streets throughout the weekend.

The anniversary ceremony is scheduled to take place on Sunday, September 11, at the World Trade Center construction site from 8:30 a.m. to 2 p.m. The security perimeter will be expansive, the better to protect attendees, such as President Barack Obama and former President George W. Bush.

Here are the closures we know of now. WNYC will update this list as we learn more.
