TULSA, Oklahoma - Several Oklahoma highways remain closed Friday because of flooding and if drivers ignore those barricades, it could be costly.

The Oklahoma Department of Transportation says Highway 20 east of Skiatook and Highway 11 at 136th Street North in Tulsa County are closed.

In Nowata County, Highway 10 east of Lenapah is impassible because of flooding.

ODOT says drivers are cautioned to heed warning signs and to not drive around barricades. 

In 2011, the Oklahoma Legislature enacted a law allowing emergency services to seek reimbursement for responding to anyone who ignores barricades and drives into flood waters.
