The extremely cold temperatures that began over the weekend in most parts of the U.S. is forcing some state departments of transportation to rethink their winter weather plans.
The frigid weather — which, according to a Huffington Post report, is called a “polar vortex” — could break wind chill records in many states as far north as Montana to and as far south Alabama.
The Missouri Department of Transportation (MoDOT) is among the state DOTs making operational changes due to severe winter weather.
St. Louis-based news station KSDK reports that MoDOT is now clearing state roads using techniques that are different from usual. Rather than plowing with salt and chemical treatments, which KSDK notes is ineffective with frigid weather, the agency has begun using sand and cinders for traction on roadways covered in snow.
However, the cold temperatures are affecting more than just roadways. The cold weather has also caused problems for some train passengers.
NBC Chicago reports that Amtrak experienced major delays Sunday and has canceled several train services today.
