Abstract
Abstract An illuminated safety curbing construction which utilizes a diving bell configuration to protect illuminators from damage by water entering the structure and employing hidden fastening means to secure its translucent cover to its base. Single- or doublefaced elongated illuminated curbing sections are adapted to be combined in various configurations with a nose section to form curbings and dividers for different traffic separator situations. Special fastening means provide flexibility and ruggedness to withstand the impact of vehicle wheels.
