ABSTRACT:
A roadway barrier (10) secured to the upper surface of a roadway (12) is formed of a plurality of half sections (20). The half sections (20) form a plurality of modules (18A-18E) positioned in two back to back columns (14A-14B) on the roadway (12). The half sections (20) and associated modules (18A-18C) in one column (14A) are staggered with respect to the half sections (20) and associated modules (18D-18E) in the other column (14B). A cable (44) for each module extends through aligned axial passages (36) in the associated half sections (20) to connect the half sections together. Bolts (66) are received within aligned transverse passages (32) in back to back half sections (20) to connect the two columns (14A, 14B) to each other. Shock absorbing means (60, 68) are mounted between cables (44), bolts (66) and the connected half sections (20) to permit a cushioned movement of barrier wall (10) upon impact of a moving vehicle.
