Abstract: An improved traffic channeling device for positioning on a highway in a normal traffic flow pattern. The improved device comprises a generally paperboard shell structure which has formed on its lower portion an inwardly folded flap structure. An inner cap like structure is positioned within the device and is positioned in contact with the lower inner periphery of the shell and the inwardly folded flap structure to act as a means to aid in the forming of the device in its predetermined shape. The inner cap like structure serves also as the means to support an object positioned over the flap structure to hold the shell structure in a predetermined position on the highway. The outside of the shell structure contains warning means for warning the traffic flow that the device has been positioned on the highway with the warning means comprising in the preferred embodiment an adhesive reflecting tape being applied to at least a portion of the outside of the shell structure.
