New details have come out about the accident on I-24 last Wednesday, where an over-sized dump truck hit part of the Moore Road overpass.

The 911 caller says the driver was traveling from downtown with a company truck, but after it happened, she called her employer before police were notified of the incident.

I-24 East was shut down for 12 hours as TDOT crews made repairs.

"One of our drivers hit the bridge with a track hoe boom that was left up,” the caller said.

The driver, Beverly Cross, called work before reaching out to the police.

A worker with the construction company went out to the scene and called the police about the crash.

TDOT engineer Joe Deering says eight of the 24 strings on the bridge were severed and more repairs are needed in the future.

"It's on the interstate. They hit the bridge. I got on the track hoe after she called me out there, lowered the boom and had her pull off at East Ridge to get off the interstate,” the caller said.

Cross was cited for the truck being over height.

The Tennessee Highway Patrol says truck drivers need certain permits to haul loads higher than 13 feet.

In a press conference two days later, they say there is no reason for companies to not be in compliance with the law.

Management from the company says they take responsibility and want to do everything they can to make sure this never happens again.

The person who made the call said Beverly did the right thing by notifying the company before the police.

The company says they are taking extra steps to ensure their drivers are better trained and safer on the roads.
