NEW ORLEANS – As New Orleans prepares to reopen Bourbon Street to the public after the deadly truck attack on New Year’s Day, Louisiana Gov. Jeff Landry said it is an “unprecedented” event ahead of Thursday’s Allstate Sugar Bowl. There will be a police presence.

At a news conference Thursday, New Orleans Mayor LaToya Cantrell said the city would reopen Bourbon Street to the public at 3:30 p.m. ET on Thursday, a half-hour before No. 2 Georgia and No. 7 Notre Dame is scheduled to play in a college football playoff quarterfinal game in the Sugar Bowl.

The Sugar Bowl was originally scheduled to take place on Wednesday night, but the game was postponed a day after a deadly pickup truck attack on Bourbon Street left 14 people dead and dozens more injured.

The FBI said Thursday it believes the driver of a truck that drove around a police line and struck a crowd on Bourbon Street in the early hours of New Year’s Day acted alone.

“I want to reassure (reassure) people that an unprecedented amount of law enforcement resources are currently being deployed in the city of New Orleans to solve, locate and complete this investigation,” Landry said.

Landry said members of the Louisiana National Guard, as well as correctional officers and members of other state law enforcement agencies, were deployed to the city to assist with security.

In an interview on “Today” Thursday, New Orleans Police Commissioner Anne Kirkpatrick said the city would have as many security measures in place for the Sugar Bowl as it planned for next month’s Super Bowl.

“We work with a lot of other partners,” Kirkpatrick said. “Both local police, federal police, military police, etc. will be here and that is why we will have hundreds of officers and personnel lining our streets, Bourbon Street and the French Quarter. So we’re adding to our staff at the same level, if not better, than we prepared for the Super Bowl.

Scores of security officers were around the 70,000-seat stadium on Thursday dealing with dogs trained to sniff for explosive devices. They surrounded cars entering the Superdome parking garage and, in some cases, sniffed bags and backpacks.

Flags hung outside the Superdome and on nearby state buildings.

Christopher Raia, deputy assistant director of the FBI’s Counterterrorism Division, said federal agents had completed their investigation on Bourbon Street and turned the area over to the city.

Raia said the FBI believes at this point that the driver of the truck – identified as 42-year-old Shamsud-Din Jabbar, a U.S. citizen and Army veteran from Texas – acted alone in the attack.

“We do not believe at this point that anyone other than Shamsud-Din Jabbar is involved in this attack,” Raia said.

The attack, which also injured more than 30 people, occurred around 3:15 a.m. CT on Wednesday in the French Quarter, known worldwide as one of the largest destinations for New Year’s Eve parties. The vehicle struck a crowd on Bourbon Street, and after it came to a stop, Jabbar got out of the truck and opened fire on responding officers, New Orleans police said.

The officers returned fire, striking Jabbar and killing him, police said.

Raia said the FBI located two IEDs in the French Quarter and obtained video footage that showed Jabbar placing coolers containing the IEDs at various locations in the French Quarter before the attack.

After Jabbar planted the explosive devices, he changed his clothes, multiple law enforcement sources told ABC News. ABC News said the FBI was still investigating whether there were people Jabbar spoke to or messaged before the attack early Wednesday, but no one was around to help him with anything, the sources said.

Raia said the FBI seized three cell phones and two laptops used by the driver as part of its investigation.

“We do not believe the public is in danger in these locations,” Raia said.

City workers cleaned Bourbon Street Thursday morning. Shortly thereafter, delivery trucks and employees of businesses in the entertainment district were allowed into the area.

Kirkpatrick said additional security measures would be taken in the French Quarter on Thursday. Police said Jabbar was able to bypass police lines and drive onto Bourbon Street. A project has been underway in the city to remove and replace bollards – post-like barriers designed to prevent vehicles from entering the area. They weren’t there for the Sugar Bowl yet.

New Orleans will host Super Bowl LIX on February 9th.

“Well, they couldn’t be operational, and that’s because it was repaired,” Kirkpatrick said. “We were aware of this problem and therefore deployed patrol cars. That will change today. We will have much heavier equipment to defeat these softer targets. The city had a multimillion-dollar package to repair this infrastructure, but it was not yet complete at the time of this event last night.

The Bulldogs and Fighting Irish are expected to leave their hotels for Caesar’s Superdome about two hours before kickoff. A Georgia official told ESPN that the Bulldogs would return to Athens, Georgia, on charter flights after the game. The Fighting Irish were also expected to head to South Bend, Indiana, after the game.

The winner of Thursday’s game will face No. 6 Penn State in the CFP semifinals on Jan. 9 at the Capital One Orange Bowl in Miami Gardens, Florida.
