Abstract: Roadway barrier system which provides a safe separation between opposing lanes of vehicular traffic and in some embodiments is capable of being moved across a lane to change the direction of traffic flow in the lane. In one disclosed embodiment, side plates bridge the gaps between the ends of adjacent barrier sections and providing a continuous surface along the sides of the sections. In some embodiments, striation panels are help dissipate the energy of vehicles which contact the barrier and to assist in preventing such vehicles from bouncing off or climbing over the barrier.

Abstract: Roadway barrier system which provides a safe separation between opposing lanes of vehicular traffic and is capable of being moved across a lane to change the direction of traffic flow in the lane. A plurality of barrier sections are positioned end-to-end along one side of the lane, and a vehicle which travels along the lane has a transfer beam in the form of a figure-8 with a portion of the beam extending diagonally across the lane for transferring the barrier sections from one side of the lane to the other as the vehicle travels along the lane. Hinged connections between the barrier sections permit the sections to be positioned different distances apart and at different angles relative to each other, and striations on the side faces of the barrier sections help to prevent vehicles which contact the barrier sections from climbing over the barrier.

Abstract: A moveable roadway barrier system comprising a number of interconnected barrier sections of substantial length which can be moved to change the direction of traffic flow or for other reasons by a self-propelled or towable vehicle without disconnecting adjacent barrier sections. Barrier sections which have glare screens or other devices protruding above the top of the barrier can be transferred by the system. Existing barrier sections of various lengths and profiles can be retrofitted for transfer by the system.
