A rockslide including a large boulder has forced the closure of a portion of one of Oklahoma's busiest thoroughfares after a night of heavy rains.
The Oklahoma Highway Patrol has indefinitely closed the northbound lanes of Interstate 35 in Murray County following a downpour in the area. Troopers say a vehicle struck the large boulder that rolled down from the Arbuckle Mountains and that at least one person suffered unspecified injuries.
Smaller rocks are continuing to fall in the area.
Murray County was one of the hardest areas hit by Tropical Depression Bill overnight. National Weather Service meteorologist Vivek Mahale in Norman says the storm dropped 6 and 11 inches of rain on portions of Murray and Carter counties.
The service has issued a flash flood watch for the eastern half of the state that is expected to last into the evening.
