A four-car pile-up on Pecos Road Thursday evening closed the road during rush-hour between 32nd and 24th streets.
"I am absolutely amazed no one died in this," said Sgt. Mark Humbles.
Police were still investigating the crash that sent two to the hospital, one with a broken collar bone and the other as a precaution.
According to police officer Joe Wennes, the preliminary information indicated that two vehicles heading west were driving aggressively when one changed lanes and clipped a vehicle. A third vehicle was hit and spun into the median, went airborne and hit a eastbound vehicle.
"Fortunately it looks like everyone had their seat belts on," Wennes said.
The crash comes a week after Brian P. Evans of Chandler died when his sedan swerved into oncoming traffic and crashed into a dump truck.
Pecos was expected to be closed until 8 p.m. or more, as crews removed two vehicles that were totaled and officers investigated the scene.
