ABSTRACT:
A lane barrier system comprises a plurality of pivotally interconnected modules adapted to be transferred on a roadway. Each adjacent pair of modules are pivotally connected together by a hinge connection to permit the modules to elongate or contract to assume a composite varied length different from a nominal length. The controlled elongation or contraction of the lane barrier system is particularly advantageous when the barrier is positioned at various radii on a curved roadway. Each hinge connection is preloaded, such as by a torsion spring, to positively return the pivot axes of the hinge connections to their nominal positions and the lane barrier system to its nominal length when they are loaded onto a transfer machine for subsequent placement on a roadway.
