Throughout and after a long day of snowfall throughout the Sooner State, the Oklahoma Department of Transportation is working around the clock to clear the roads and give motorists a safe drive."Our crews will be out for some time trying to get everything clear, and they'll stay out until it's completely gone," ODOT spokeswoman Brenda Perry said.According to Perry, ODOT had more than 500 trucks across Oklahoma clearing the roads. She urges drivers to still take caution, especially Thursday morning."Tomorrow morning could be one of the more slick times because all of this that is getting driven on now is becoming a little slushy," Perry said. "Sometimes, it can even be days after a storm has stopped before it becomes completely clear. So, we just want people to realize that and realize that it is going to take some extra time if they have to travel."Perry told KOCO 5 that once ODOT knows a storm is coming, crews start preparing and looking for different methods to treat the road."We have a brine solution that is something that we can put out that helps the clearing process, kind of become a barrier and just helps the melting process as we're out clearing the roads," Perry said. She said anyone who sees an ODOT crew clearing the road sould give them some space and stay back about 200 feet for their and your safety."They have clearance equipment on there that they're pushing the snow off to the side," Perry said. "Sometimes, they're putting down sand and the salt, and so things can be coming off of that."
