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.

1. In a roadway barrier system (11) which includes,at least two barrier sections (13) positioned end to end on a roadway surface (12) of a roadway with a joint (16) defined between ends of said barrier sections, two connectors (14) positioned on opposite lateral sides of said barrier sections with each said connector overlapping ends of said barrier sections at said joint, and fasteners (17, 20, 21, and 22) extending laterally through said connectors and said barrier sections, wherein the improvement comprises, a bracket (15) having a vertical fin (25) and a horizontal base (26) having a hole (23) formed in said horizontal base, said vertical fin slideably disposed between at least one of said two connectors and a portion of at least one of said lateral sides of said barrier sections, said horizontal base of said bracket extending laterally outwardly from said two barrier sections on said roadway surface, and a bolt (18) extending through said hole of said horizontal base of said bracket into said roadway. 2. A roadway barrier system of claim 1 further comprising,first and second shims (19) with said first shim positioned longitudinally forward of said bracket (15) between said at least one of said two connectors and said lateral side of first of said barrier sections and said second shim positioned longitudinally aft of said bracket between said at least one of said two connectors and said lateral side of second of said barrier sections. 3. A roadway barrier system of claim 1 wherein,said horizontal base of said bracket having said hole formed therein extends laterally outwardly from said two barrier sections on said roadway surface such that said bolt extending through said hole of said horizontal base of said bracket into said roadway is positioned laterally outwardly from said at least one of said two connectors. 4. A roadway barrier system of claim 1 wherein,said vertical fin of said bracket is disposed between said at least one of said two connectors and said two barrier sections such that said bracket longitudinally overlaps said joint. 5. A roadway barrier system (11) comprising,at least two barrier sections (13) positioned end to end on a roadway surface (12) of a roadway with a joint (16) defined between ends of said barrier sections, two connectors (14) positioned on opposite lateral sides of said barrier sections with each said connector overlapping ends of said barrier sections at said joint, a bracket (15) having a vertical fin (25) and a horizontal base (26) having a hole (23) formed in said horizontal base, said vertical fin slideably disposed between at least one of said two connectors and a portion of at least one of said lateral sides of said barrier sections, said horizontal base of said bracket extending laterally outwardly from said two barrier sections on said roadway surface, a bolt (18) extending through said hole of said horizontal base of said bracket into said roadway, and fasteners (17, 20, 21, and 22) extending laterally through said connectors and said barrier sections. 6. A roadway barrier of claim 5 further comprising,first and second shims (19) with said first shim positioned longitudinally forward of said bracket (15) between said at least one of said two connectors and said lateral side of first of said barrier sections and said second shim positioned longitudinally aft of said bracket between said at least one of said two connectors and said lateral side of second of said barrier sections. 7. A roadway barrier system of claim 5 wherein,said horizontal base of said bracket having said hole formed therein extends laterally outwardly from said two barrier sections on said roadway surface such that said bolt extending through said hole of said horizontal base of said bracket into said roadway is positioned laterally outwardly from said at least one of said two connectors. 8. A roadway barrier system of claim 5 wherein,said vertical fin of said bracket is disposed between said at least one of said two connectors and said two barrier sections such that said bracket longitudinally overlaps said joint. 9. A method of installing a roadway barrier system (11) comprising,positioning at least two barrier sections (13) end to end on a roadway surface (12) of a roadway with a joint (16) defined between ends of said barrier sections, placing two connectors (14) on opposite lateral sides of said barrier sections with each said connector overlapping ends of said barrier sections at said joint, installing a bracket (15) having a vertical fin (25) and a horizontal base (26) having a hole (23) formed in said horizontal base, such that said vertical fin is slideably disposed between at least one of said two connectors and a portion of at least one of said lateral sides of said barrier sections, and such that said horizontal base of said bracket extends laterally outwardly from said two barrier sections on said roadway surface, installing a bolt (18) through said hole of said horizontal base of said bracket into said roadway, securing said two barrier sections, said two connectors and said bracket with fasteners (17, 20, 21, and 22) extending laterally through said two connectors and said barrier sections. 10. The method of claim 9 further comprising the steps of,installing a first shim (19) longitudinally forward of said bracket between said at least one of said two connectors and said lateral side of first of said barrier sections, and installing a second shim longitudinally aft of said bracket between said at least one of said two connectors and said lateral side of second of said barrier sections. 11. The method of claim 10 further comprising the steps of,positioning said vertical fin of said bracket between said at least one of said two connectors and said two barrier sections such that said bracket longitudinally overlaps said joint.
