Tulsa emergency crews worked two overnight rollover wrecks. One took place Friday morning on Interstate 44 at the Broken Arrow Expressway bridge overpass.
Officers say a 35-year-old woman was eastbound when she hit the concrete barrier wall, causing her car to flip and land on its top.
There was no word on what caused the crash, but she wasn't injured.
An earlier rollover wreck took place around 11:15 Thursday night on the Highway 169 exit ramp from Interstate 44.
One person is in the hospital after that crash.
Police say the driver was going too fast, went over the curb and rolled several times. Two other juveniles in the vehicle were not hurt.
No other vehicles were involved.
