ABSTRACT:
A moveable highway barrier includes a hinged shell and a stationary barrier section. The stationary barrier section contains a mechanism for raising the hinged shell between a standard position (also known as the lowered or closed position) and an open position (also known as the raised position). When the hinged shell is in the open position, vehicles, such as emergency vehicles, can traverse through the opening. The hinged shell can overlap a neighboring fixed barrier to provide lateral support. Additional support can be achieved through the use of a gravity or spring-loaded pin engaging with a hole in the ground. The system is signalled by a remote control.
