A hurricane evacuation exercise on Route 72 and other highways in the Jersey Shore area on Thursday, June 6, will not close roads, authorities said, but “motorists should expect an increased police and work crew presence on key shore routes.”

The main element of the exercise is preparing to set up what is termed a “contra flow,” which is reversing traffic on a section of roadway to travel in the opposite direction, on highways that serve as evacuation routes for the shore.
