ABSTRACT:
A median barrier for highways separating two vehicle-travel lanes comprises a plurality of preferably breakaway posts forming a rigid center wall and, mounted on the latter, a pair of deflectable guard rails spacedly flanking this wall. Arms extending from the central wall carry the guard rails and are swingable about vertical axes. The central wall is constructed to extend sufficiently high so as to be effective for trucks and other large vehicles while the guard rails are positioned for maximum effectiveness with passenger automobiles.
