Abstract: A barrier for a roadway (e.g., a highway, bridge, or other road), which can be used to manage vehicular traffic, such as to establish lanes, protect motorists and other people (e.g., pedestrians, constructions workers, etc.) against crashes or other impacts, and/or other purposes, and which may be configured to enhance its use and performance, such as by better protecting the motorists and others when impacted by vehicles (e.g., reducing deflection by deflecting less or substantially not deflecting and/or otherwise improving protection provided by the barrier), facilitating transportation, installation, removal, and/or transfer of the barrier at the roadway, and/or enhancing other aspects of the barrier. For example, the barrier may be designed to protect against (e.g., prevent or reduce) deformation, breakage and/or other deterioration of interfaces (e.g., connections and/or interfacing material) of components of the barrier that may move relative to one another (e.g., when impacted by vehicles).
