TULSA, Oklahoma -- City of Tulsa crews will continue to salt city streets Thursday night.
The city has 55 trucks on the roads all over town, many with a snow plow on the front end and a salt spreader on the back.

The Oklahoma Highway Patrol temporarily closed a section of westbound Interstate 40 in Checotah in McIntosh County after several semis left the roadway, blocking traffic. They warned that the roadway is ice covered, slick and hazardous.
