Five people were injured in a major rash Saturday evening between two passenger vehicles and two 18-wheelers in the 1100-block of N. Interstate Highway 35.

Officials said around 6:10 p.m., first responders were called to the crash with reports of possible entrapment.

An investigation of the crash found a DBI employee was repairing a pothole in the southbound lanes. As the employee crossed I-35 on foot, a red Ford pickup stopped in the lane of traffic causing an 18-wheeler to stop quickly to avoid collision with the pickup. A red Chevy Traverse also braked hard but was partially rear-ended by the second 18-wheeler – pushing the traverse under the first 18-wheeler. After hitting the Traverse the 18-wheeler swerved into another lane sideswiping a blue 2016 Mazda 3.

Responders found seven people inside the Traverse with two of the occupants trapped in the vehicle.

It took Waco Fire and EMTC over an hour to extricate the entrapped. The Traverse driver was taken to Hillcrest ER with critical injuries and three other occupants were transported for minor injuries.

The southbound lanes of I-35 were closed for more than four hours before reopening. Waco Fire Hazmat were also dispatched due to a ruptured fuel tank in one of the trucks. Grones Environmental Services also assisted in cleanup.
