Grayson County and Fannin County drivers may encounter road crews, lane closures and slow-moving traffic this week as Texas Department of Transportation crews carry out road-improvement projects across the region.

“Motorists are advised to remain alert and pay special attention to all signs, barricades and traffic controls, and reduce their speed as they approach and travel through work zones,” TxDOT said in an emailed news release. “They should also avoid distractions such as cell phones, eating, drinking, or car audio or navigation systems.”

Completion of the following projects may be delayed due to weather conditions, machinery failure or other issues.
