RALEIGH, N.C.  – North Carolina State Police are asking for those going to Tuesday’s Beyoncé concert to be ready for some serious traffic.

An estimated 40,000 fans are going to cram into Carter-Finley Stadium to see the pop superstar just days after she dropped a surprise album.

Signs are already up around the stadium warning drivers to expect major delays.

“The show doesn’t start until 7:30, but we’re coming from Morrisville, which is about 20 minutes away. But I think we’re going get on the road about 4:30,” said concert-goer Cynthia Wynn.

Wynn stopped by the stadium box office Monday to learn more about traffic and parking.

“I’m coming with my 7-year-old. I want to make sure things are going to flow and be as easy as possible,” Wynn said.

Police said the traffic pattern will be identical to that of an N.C. State football game and law enforcement will be directing traffic around the stadium.

Police are actually expecting around 20,000 fewer people than they do for a football game but the addition of rush hour traffic is a recipe for a nightmare.

Drivers are asked to stay away from the area if they aren’t attending the concert.

U2 and the Rolling Stones are the only two acts to play at Carter-Finley in the last several years.

Police are hoping to avoid the traffic nightmare that occurred when U2 played in 2009.

Some ticketholders missed the U2 concert due to the high volume of traffic. Officials said the problems stemmed from too many people trying to arrive at the same time.

DJ Khaled starts the show at 7:30 p.m.

Tickets are still available for the show.
