For this project, the research team at NAU worked with ADOT and independent consultants to develop a span wire specification and standard drawing set for the Traffic Signals and Lighting division of ADOT. The team research typical intersection geometries, equipment weights, signal head requirements, and other states’ span wire specification from across the country in developing a standard / specification that is unique in that it can be implemented by a designer; if one stays within the constraints set forth in the general conditions, no structural engineer is needed.
