Grayson County and Fannin County drivers may encounter traffic pattern changes and delays this week as the Texas Department of Transportation carries out road-improvement projects in the area.


“Drivers are reminded to avoid in-car distractions, such as cellphones and entertainment systems, and remain aware of possible lane shifts, road closures and slow-moving equipment and vehicles,” a news release from the department said.


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