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.
