Drivers who might be taking the Clearview Expressway tonight, we received this alert about the Clearview/73rd Avenue exit: "The Federal Bureau of Investigation, New York City Police Department, U.S. Department of Energy, and the U.S. Department of Defense will be conducting a routinely scheduled, joint interoperability full scale training exercise in the New York City area during June 9-11, 2009. Resources from a variety of federal, state and local agencies will be participating to test and determine compatibility and response proficiency. Please be advised that due to this full scale exercise, traffic delays are anticipated on the Clearview Expy. between the hours of 9 PM on Tuesday, June 9th and 4 AM. on Wednesday, June 10th, 2009." There will also be some exercises through Thursday (we're assuming Wednesday night through early Thursday morning.) About 300 cops and almost 400 FBI agents and analysts are participating and Police Commissioner Ray Kelly says the drill will "address the possibility of a nuclear or radioactive device coming into the city." (Yes, like a dirty bomb.)
