A Winter Storm Advisory is in effect through noon on Monday.
Weather conditions were expected to deteriorate Sunday afternoon across North Texas. As temperatures get to the freezing point, it is possible to see icing on area roadways starting with bridges and overpasses.
The Texas Department of Transportation started pre-treating elevated highways on Interstate 20 and Interstate 30 in Dallas County starting at noon Sunday. TxDOT trucks were also out in rural areas around Tarrant County checking for slick spots.
"The first thing we attack are bridges," TxDOT spokesman Ryan LaFontaine said Friday. "We have more than 3,300 bridges throughout this district, and there are some that are worse than others as far as freezing."
TxDOT said the Dallas and Fort Worth districts have stockpiles of chat, a sand-and-salt mixture, and salt-based de-icers prepared for winter conditions.
TxDOT urges drivers to use caution and watch for patches of ice, especially in shady areas and on the shoulders of roadways.
Drivers can get travel information by calling 1-800-452-9292 or by visiting www.drivetexas.org.
Meanwhile the City of Dallas has enacted "Ice Force One." According to Dennis Ware, Interim Director of Dallas Department of Street Services, 30 sanding trucks will continue non-stop 12-hour shifts focusing on bridges, overpasses, ramps and major intersections. The city stepped down precautions to change to "scout" mode -- monitoring and targeting specific overpasses with de-icing equipment.
Citizens are urged to call 3-1-1 to report icy areas but remember the city does not treat residential streets.
