HARRIS COUNTY, Texas – A bizarre standoff with a naked woman dancing on top of a big rig brought traffic on US-290 to a halt Monday morning.

The westbound lanes of the highway were shut down for more than two hours while the woman entertained drivers stuck in the standstill.

Views from Air 11 showed the woman twerking and gyrating for passing vehicles just after 9 a.m.

It was part of a service call that Cy-Fair volunteer firefighter Brian Shirley will never forget.

"You're thinking on your feet the whole time," Shirley said. "We wanted to get her down safely."

Firefighters and police officers used ladder trucks to try and coax the 25-year-old woman down, but she cursed at them and refused to budge. They finally jumped on the top of the big rig and wrestled her into the ladder bucket.

Houston TranStar reports the dancing woman was preceded by a crash involving three vehicles. It's believed the woman was driving one of the wrecked cars.

Shirley stood next to the big rig as first responders tried to negotiate with the woman.

"She wasn't making any sense. A lot of times she was real quiet, but then she had outbursts about the FBI and the CIA is after her," Shirley said.

Pearly Ward saw the whole thing unfold and called 911.

"That's the most horrific thing I've ever seen, and I'll be 68 in two days," Ward said.

The woman was taken to an area hospital for a mental health evaluation.

While her dance moves lead to a lot of laughs Monday, Ward and others were praying for her well-being.

"And I said, 'In the name of Jesus I bless you and hope things will be okay for you,'" Ward said.
