The Oklahoma Department of Transportation has closed lanes on Highway 412 just west of downtown Tulsa for emergency repairs.
ODOT says the two left lanes of westbound Highway 412 are closed near Gilcrease Museum Road until further notice.
It expects the closure to be in place through the evening rush hour.
The work will probably cause significant delays so ODOT recommends drivers take an alternate route.
ODOT hasn't said what caused the damage to the pavement.
