ABSTRACT:
A traffic barrier is movable to vary the number of lanes available for vehicles and is sufficiently sturdy to withstand collisions from vehicles and direct them back into the flow of traffic rather than permitting hazardous crossovers, which often result in head-on collisions. A plurality of panels are configured to be positioned in a side by side array between two roadway sections so that their lengths are generally parallel to the roadway. The panels are preferably connected by a plurality of hinges arranged for hingedly connecting adjacent barrier panels together. A first barrier is erected by hinging a pair of the panels toward one another on a first side of the roadway and providing a traffic lane over the array on a second side of the roadway. The first barrier may be removed and a second barrier on the second side of the roadway and a traffic lane over the array on the first side of the roadway may be formed by elevating a second pair of the barriers panels.
