ABSTRACT:
A traffic barrier gate for controlling the flow of vehicles through a barrier, such as a concrete median wall between opposing traffic lanes of a controlled access highway. In one embodiment the gate comprises hinged sidewall panels connected to a support member which is moved vertically on command and which, when moved, causes the sidewall panels to collapse and spread out thereby forming a ramp for the passage of vehicles through the wall barrier. In a second embodiment, the gate revolves 180.degree., upon command, and then retracts into a well in the ground thereby forming the traffic ramp.
