flyover
n.— «The prospect of an overpass that will eliminate the traffic circle by fall 2006 infuriates the native Cape Codder.…They argue that the rotary can handle more cars than the bridge, making the bridge the traffic problem, not the rotary—many Cape residents and businesses believe the flyover will ease traffic headaches by keeping traffic moving.» —“Flyover leaves some in dust” by Naomi Aoki Boston Globe May 26, 2005.
