Atlanta-Based. Lowcountry Ready.

AQC Traffic Control is a Southeast-focused traffic control company based in Atlanta — roughly five hours from Charleston via I-26. We provide certified flagging, lane closures, traffic control planning, and equipment rental for contractors, utilities, and municipalities throughout Georgia and the broader Southeast, including Charleston and the South Carolina Lowcountry.

Every flagger we field holds current ATSSA certification. Every work zone is built to SCDOT standards. Whether your project is a utility repair on a congested peninsula street, a multi-lane closure on I-526, or a TCP for a port-adjacent corridor in North Charleston, we handle it from planning through final closeout.

You won't spend time waiting on a regional dispatcher when you call AQC. You'll reach the people managing your project directly — faster responses, cleaner coordination, and clear accountability from start to finish.
