Traffic in both the north and southbound lanes of Interstate 35 was moving at a crawl Thursday morning after an 18-wheeler crash in Salado.

According to TxDOT officials, a FedEx truck headed south lost control on the highway near Thomas Arnold Road shortly before 2AM and crashed into a concrete barrier before bursting into flame.

A driver and trainee aboard the vehicle were able to escape and are said to be in good condition.

North and southbound traffic was diverted for hours as hazmat crews worked to clean the area.

As of 9:15 AM, traffic was still slow along I-35. Drivers are encouraged to find alternative routes.
