The truck had a trailer attached carrying three Mercedes Benz SUVs that all overturned.
The Research Park overpass, typically four lanes, went down to one lane. The two outside westbound lanes of University under Research Park have been re-opened to traffic.
Huntsville police and Huntsville Fire and Rescue responded to clear the scene.
Byron Steward, the sales manager at the Mercedes Benz Huntsville dealership, said this is an unfortunate turn of events. He said the vehicles were being delivered for customers to pick up.
"That's a tough phone call to have to make to those customers," Steward said, "but we will go back to the drawing board and find something comparable to replace those vehicles with."
The vehicles being carried on the truck that overturned were coming from North Carolina, South Carolina, and Atlanta. Steward said the price of the vehicles totals around $200,000.
