Traffic along northbound I-35 in Temple was at a standstill Wednesday morning after an 18-wheeler overturned.

The wreck occurred shortly after 7 AM near Exit 303. Traffic was being detoured at the Industrial Blvd exit near the Carpenter building as an environmental remediation company worked to clear diesel fuel and other chemicals from the crash site.

Thomas Pechal with Temple Fire & Rescue estimated it would take 2-3 hours to clear the scene and reopen northbound lanes.
