Abstract: A roadside standard assembly and maintenance method are provided which facilitate installation, maintenance, and repair of an object suspended over a roadway. The standard assembly comprises a support pole and an arm extending from the pole. The object is supported on the arm, and is normally disposed over a roadway. The standard rotates about the pole, allowing the arm to swing from over the roadway to a roadside position from which the object can be accessed for maintenance without resorting to a road closure. An anchoring structure maintains the upward orientation of the pole, and is optionally retrofittable for existing roadside standard installations.
