New Orleans residents should be aware of parking instructions and traffic reminders in advance of this week’s New Year’s Eve and Allstate Sugar Bowl celebrations, city officials said Tuesday.

The public is encouraged to be patient and prepare for delays Wednesday through Friday.

On Wednesday, the Allstate Fan Fest will begin at noon at 418 N. Peters St. and last until 8 p.m., with a concert by recording artist Usher at 6:15 p.m. New Orleans police will be monitoring pedestrian crowds in the French Quarter and will divert vehicular traffic if necessary.

On Thursday, New Year’s Eve, the second day of the Fan Fest will begin at noon on North Peters Street, followed by an Oklahoma State University pep rally at 1:30 p.m. Two hours later, the Sugar Bowl/New Year’s Eve Parade will begin at Elysian Fields and Decatur Street, proceed down Decatur Street past Jackson Square and then along North Peters Street to Canal Street, where it will disband.

Because of New Year’s Eve celebrations that night, Decatur Street will be limited to one lane of traffic each way from Dumaine Street to St. Louis Street until 2:30 a.m. Friday. Police, who will divert vehicular traffic if necessary, encourage drivers to avoid this area.

On Friday, New Year’s Day, the Allstate Sugar Bowl Fan Jam will begin at 4 p.m. in Champions Square next to the Merecedes-Benz Superdome. The game pitting Oklahoma State against the University of Mississippi will begin at 7:30 p.m.

Police will divert traffic if necessary, and parking enforcement personnel will be monitoring for illegal parking, including blocking hydrants, driveways and sidewalks, or parking within 20 feet of a crosswalk, intersection or stop signs.

Motorists are also reminded to park in the direction of travel on one-way streets and with the right wheel next to the curb on two-way streets.

The events also may affect Regional Transit Authority service times. Check for route changes.
