Ice on roadways in southern, central and western parts of the state is causing travel problems, the Oklahoma Highway Patrol reported.
Authorities are discouraging travel on state highways and interstates.
State Department of Transportation crews report numerous closings on rural highways due to downed trees and power lines. Affected areas are in a band from Harmon County in the far southwest part of the state and continuing northeast through the central part of the state to Lincoln County, a department news release said.
Areas near Altus, Lawton, Duncan, Chickasha, Pauls Valley, Purcell and Stroud are most affected. Also, Texas officials report poor conditions near Stratford, Texas, and have requested highways leading from Guymon and Boise City in the Oklahoma Panhandle be closed.
The state Transportation Department said most of Interstate 40 west of Oklahoma City to the state line is slick and hazardous.
Interstate 35 southbound near Billings is now open. A seven-car accident shut down the road for more than an hour.
Here are some of the highways that have been closed:
- U.S. 62 from Altus to Duke and at the Highway 6 junction have been closed due to power lines, troopers said.
- Northbound U.S. 81 near Duncan at Terry Road and southbound U.S. 81 at Fuller Road have closed as well.
- The H.E. Bailey Turnpike from Elgin to Chickasha has been shut down due to power lines. Southbound traffic from Oklahoma City is being diverted to U.S. 62.
- State Highway 7 east of Second Street in Lawton has also been closed to the State Highway 65 Junction.
- U.S. 54 has been closed at Guymon per request of the Texas Department of Transportation.
- U.S. 277 at King Road north of Fletcher in Comanche County is shut down to Cyril in Caddo County due to power lines in the roadway.
City crews busy
Oklahoma City crews were salting roads with 24 trucks all day, city officials said. The biggest concern is trucks breaking down, which hampered clean-up efforts in last month's blizzard.
"As long as nobody breaks down we'll have 24 trucks out 24 hours," city spokeswoman Kristy Yager said.
Although the roads started to worsen in the afternoon, the city seemed to dodge the worst of the weather early in the day, Yager said. Ground temperatures helped melt freezing rain as it hit the streets.
"Everybody feels like, so far, we've gotten pretty lucky," Yager said.
