A portable security system comprises two security units, located on opposite sides of a roadway or other path for vehicles, each consisting of at least two hollow barrier devices filled with a ballast material such as water, sand, chunks of rubber or the like. Adjacent barrier devices in each security unit are interconnected side-by-side, and a cable spans the two security units which is movable between an open position permitting the passage of vehicular traffic along the roadway and a closed position.
