Speeders and red-light runners would do best to avoid 21st Street — or, you know, slow down and obey traffic laws — till this morning.

The Wichita and Andover police departments, Sedgwick County Sheriff's Office and Kansas Highway Patrol worked together on a traffic crackdown along 21st Street from Andover through Wichita to the western part of the county. It started at 7 a.m. Thursday and ends at 7 a.m. today.

Sgt. Chris McAuliffe of the Wichita Police Department said he wouldn't get totals on how many tickets were issued until later. But officers planned to focus on drivers who were speeding, running red lights, driving while impaired and not wearing their seat belts.

"It's a major thoroughfare, and we have had some higher accident locations such as 21st and Rock and 21st and Woodlawn," McAuliffe said. "We routinely get citizen complaints about some of the traffic on 21st Street."

Sgt. Troy Wells of the Sheriff's Office said traffic flow along 21st Street "is a lot different out east than it is out west."

"Normally this time of year, out west is pretty steady," he said.
