A small child and two adults are injured after a crash involving a semi-truck on Interstate 10.
At around 2 p.m. Friday, emergency crews were called to a three-vehicle crash on I-10 near Riggs Road.
Authorities say one person was trapped underneath a semi-truck. The extent of the injuries hasn't been determined.
Witnesses tell Arizona Department of Public Safety troopers that a passenger car crossed all lanes of traffic and struck the other two vehicles.
Westbound lanes were closed for a few hours following the incident and have since reopened.
An investigation remains ongoing.
