About this file

Written by GovTribe AI · Feb 5, 2026

This is a signal design file for the Georgia Department of Transportation (GDOT) detailing the installation of a temporary traffic signal at the intersection of State Route 204/Fort Argyle Road and Old River Road in Chatham County, Georgia. The project involves the furnishing of materials and labor for a temporary traffic signal installation, including minor grading, traffic signal equipment, striping, and signing. The design encompasses microwave detection systems, pedestrian detection systems with LED countdown signal heads, retroreflective backplates with LED signal heads, regulatory and warning signs, and pavement markings. Key equipment quantities include one Model 2070LX controller unit, one Model 332 prefabricated cabinet base, four microwave radar units, three pedestrian detection systems, nine signal heads (including 18-inch pedestrian countdown heads), three 10-foot pedestal poles, treated timber poles (Class 2, 45 feet), 160 linear feet of 2-inch galvanized rigid steel conduit, and 20 square yards of concrete sidewalk with detectable warning surfaces. Additional items include thermoplastic pavement markings totaling 276 linear feet of 23-inch white striping, 210 linear feet of 8-inch white striping, and miscellaneous hardware and conduit components.

The design file, prepared by GDOT with revision dates of November 26, 2025, and December 1, 2025, specifies material lists and technical specifications for contractor procurement and installation. The contractor is responsible for field verification prior to ordering materials, as noted in the design documentation. This temporary traffic signal installation is intended to serve the intersection until funding for a future roundabout project is secured. The design includes detailed phasing diagrams, signal legends, detection type specifications (magnetometer, radar, and inductive loop systems), and mounting dimensions for mast arms and signal head structures, with all materials and quantities provided for informational purposes to guide the contractor's execution of the work.
