Lance Scott recalled to FOX Weather the quick succession of crashes while on the highway.

"I happened to be in a little pocket of about probably 15 cars with no damage," said Scott. "And probably 2 or 3 seconds after we came to a stop, you just heard boom, boom, boom, boom, collision after collision behind us."

On Tuesday at 5 p.m., the Louisiana State Police said that all vehicles have been removed from both sides of I-55, and that there will be a "comprehensive structural inspection" following the cleanup.

"A comprehensive structural inspection will take place once the bridge surface is completely clear of debris, diesel, and other chemicals," state police said.

"Please join me and Donna in praying for those hurt and killed in today’s tragic I-55 crash, as well as their families. The combination of wildfire smoke and dense fog is dangerous, and I want to encourage all Louisianans in affected areas to take extreme caution when traveling," Edwards said.

The governor also encouraged residents to exercise caution while on the foggy roads and to donate blood.

"I also want to thank the first responders and medical personnel who have worked so diligently to save lives and render aid. The best way you can help them, besides exercising caution on the road, is to donate blood at your local blood donation center. It will help replenish supplies that are being drained today to care for the wounded," Edwards said.
