Roadway barrier system which resists lateral movement from roadway forces and thermal transients, accomplished by placing a plurality of restraining brackets along side a plurality of preformed concrete barrier sections. The brackets are anchored to the roadway surface. The barrier system is prevented from moving laterally away from the restraining brackets by enclosing the restraining brackets with channel beams which span the restraining brackets on the side opposite the preformed barrier sections and are secured to the preformed barrier sections with through bolts or studs. This arrangement maintains alignment of the barrier system with plan location yet allows longitudinal thermal expansion and contraction.
