BATON ROUGE - Traffic slowed to a crawl around lunchtime Thursday after an 18-wheeler caught fire and the cab exploded on I-10.

The incident happened around 11:40 on I-10 east just before the I-110 merge. The truck was on the shoulder at the Nicholson exit when it caught on fire. After a few minutes of it burning, a large fireball erupted from where the engine is located.

To battle the blaze, firefighters rushed from the other side of the divided interstate section.

There was a total closure of the interstate but eventually, lanes reopened on both sides of the interstate. Residual delays may remain.
