Description
The road traffic hazard sign is a Grade II listed structure, featuring a red-painted metal hollow equilateral triangle mounted on an ornate white-painted cast-iron post that stands 9 feet (2.7 meters) tall. The post has an octagonal shape on a square base and is topped with a flat, flared mount for the sign. Below this mount, there are moulded decorative bands, which are separated by a row of large octagonal bolts that secure the mount and create the appearance of a capital. Near the bottom of the post, between two additional moulded bands, are the letters CCM, which stand for the County Council of Middlesex, repeated on each side of the post and separated by floral studs. At the base of the post, there is an oval maker's plate that reads 'PARSONS / MAKERS / BRIERLEY HILL'.
