Abstract
A span wire assembly for supporting a traffic control device. The span wire assembly includes a pair of vertical members or cast arms for attachment to the traffic control device. The cast arms are integrally formed with tubular ends and a centrally positioned wiring passage. A span wire assembly utilizing the inventive cast arms has fewer parts and, consequently, is simpler for the manufacturer to produce and for the customer to use.
