TULSA, Oklahoma - The streets of Green Country will be revving up this weekend. The so-called reality show Street Outlaws is set to shoot part of an episode in Tulsa Saturday night. It's a series about illegal street racing.

The eastbound Port Road between East 44th Street North to North 74th East Avenue will be closed for production from 3 p.m. Saturday to 5 a.m. Sunday, and it was the city councilors that signed off shutting down the street.

Tulsa Police officers will be helping out here with the show Saturday night. It’s an area of, primarily, businesses and police said they've all been notified the shoot will shut down traffic for 15 hours.

Street Outlaws, Discovery Channel's reality series said to be about illegal racing on the streets of Oklahoma City, but in reality, it’s all staged, and apparently shot all over Oklahoma.

Most recently they shot on a state highway 20 miles west of OKC. Our cameras were rolling that night, too. But even though we were on a public street, a Union City police officer stepped in and threatened to throw our photojournalist in jail.
