Atlanta-Based. South Carolina Midlands Ready.

AQC Traffic Control is a Southeast-focused traffic control company based in Atlanta — roughly two and a half hours from Columbia via I-20. We provide flagging, lane closures, traffic control planning, and equipment rental for contractors, utilities, and municipalities across Georgia and the broader Southeast, including Columbia and the South Carolina Midlands.

Every crew we field is ATSSA-certified. Every work zone is set up in full compliance with SCDOT requirements. Whether you need one flagger for a utility cut or a full TCP for a multi-lane closure on I-20, I-26, or I-77, we handle the operation from planning through closeout.

You won't reach a dispatch center when you call AQC. You'll reach our team — the people managing your project. That means faster answers, quicker adjustments when conditions change, and no one left wondering who's responsible for getting something done.

Regional Expertise

Quick Response

Project timelines change. Weather happens. We adapt quickly because we can.
