Avoid I-20 west of Fort Worth if you can. The highway is "basically closed" west of Ranger Hill, about 80 miles west of Fort Worth. That's according to Val Lopez at the Texas Department of Transportation.
Also, in north Tarrant County TxDot maintenance crews have begun pretreating bridges and overpasses to prevent ice formation. Crews are spraying a liquid magnesium chloride to prevent icing. Later in the evening, if ice forms on the roads, the crews will spread a granular mix of sand and magnesium chloride pellets known as chat.
