Abstract: An Improved Gate Assembly is disclosed. The preferred gate assembly is constructed primarily from plastic or other resilient material that resists denting, bending, chipping, cracking, and graffiti painting. The gate assembly includes a novel mounting and hinge system from which the gates hang and swing, and which permits the pivot points to flex in order to prevent damage to the gate members themselves. The preferred gate system includes a cane bolt assembly that remains retracted while the gates are being moved, and also flexes and/or bends if the gates are struck by a vehicle. The gates include shock-absorbing bumper assemblies to prevent damage to them and may include display sections for displaying pertinent warnings or other information.
