These signal plans detail the traffic signal infrastructure project for Kimball Bridge Road and Northwinds Parkway, prepared by Moffatt & Nichol engineering firm in Atlanta, Georgia. The documents provide comprehensive technical specifications for a complex intersection upgrade, including detailed phasing diagrams, existing and proposed utility layouts, and a complete list of materials and mounting dimensions for traffic signal equipment. The project involves installing new controller cabinets, strain poles, mast arms, LED signal heads, pullboxes, conduit, and associated electrical infrastructure across multiple intersection approaches.

The technical drawings include a 332 cabinet input assignment matrix, showing intricate signal timing and configuration details for various traffic movements. The project includes specific mounting dimensions for signal equipment ranging from 12" to 30" heights, with general notes specifying sign construction requirements such as using aluminum materials, reflectorized interstate green backgrounds, and standardized mounting hardware. The plan set is professionally drafted with precise engineering details, including legends for existing and proposed utilities, detection zones, and signal equipment, suggesting a comprehensive transportation infrastructure improvement initiative focused on traffic flow and safety enhancements at this specific intersection.
