Traffic control & flagging in San Antonio, TX
GBC runs traffic control, certified flagging, and equipment rentals across San Antonio and the I-35 corridor — TxDOT-compliant closures for contractors, utilities, and events.
Austin-based, working the I-35 corridor
From our Austin yard we deploy south to San Antonio and the surrounding metro regularly — the drive down I-35 is a route our crews know well. You get the same TxDOT-compliant setups, certified flaggers, and equipment we run in Austin.
- Lane, shoulder, and full road closures
- Certified flagging crews
- Barricades, arrow boards, message boards, cones, and TMAs
- Event and special-closure traffic control
