A temporary barrier system that is configured to be placed adjacent a concrete divider on a roadway wherein the temporary barrier system provides an increased vertical barrier so as to inhibit seeing therepast. The temporary barrier system includes a storage container having the body of the present invention stored in its first position therein. The body of the present invention is planar in manner and stored in a rolled position in the storage container. The body is wrapped around a winding apparatus and includes an end that is configured to be secured to a deployment vehicle. The deployment vehicle traverses away from the storage container to deploy the body to its second position. The body further includes a plurality of support members being configured to be perpendicular to the upper and lower edge. The storage container is configured as a towable trailer.
