With the 2015 Bayou Classic in New Orleans this weekend, heavy pedestrian and vehicle traffic will affect certain parts of the city, officials said.

The Bayou Classic, which for 41 years has pitted the football teams of Southern University and Grambling State University, is expected to create big crowds through Saturday.

City officials urged the public to make appropriate transportation arrangements.

They said parking enforcement personnel will be monitoring for illegal parking, including blocking of fire hydrants, driveways and sidewalks.

Motorists also are reminded to avoid parking within 20 feet of a crosswalk, intersection or stop sign.

They must park in the direction of travel on one-way streets and with the right wheels closest to the curb on two-way streets.

From 6 p.m. to 10 p.m. Friday, the Battle of the Bands and Greek Show, in which the two universities’ bands, fraternities and sororities compete, will be held in the Superdome. There are no street closures for the event, though police officers will regulate traffic.

On Saturday, the Mercedes-Benz Superdome will host the Bayou Classic football game at 4 p.m.

Again, there will be no street closures, though police will direct traffic.

Regional Transit Authority bus and streetcar services might be interrupted during these events. Details on route changes are available at www.norta.com.
