Disclosed is apparatus for moving laterally a traffic control barrier having a plurality of pivotally linked sections. The transfer vehicle includes means for picking up the sections on one side and depositing them on the other side as it moves along the roadway. The vehicle has front and rear guide drums around which the sections are moved through the vehicle in an S-shaped path and there are means for varying the space between the axes of the guide drums to compensate for disparity in lengths of the lane dividers around a curved roadway.
