Grayson County and Fannin County drivers are likely to encounter work zones, changing traffic patterns and possible delays this week as Texas Department of Transportation crews carry out road-improvement projects in the area.


“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 statement. “They should also avoid distractions, such as cell phones, eating, drinking, or car-audio or navigation systems.”


Completion dates of the following projects may be delayed by weather conditions, machinery failure or other circumstances.
