Leave now.

That's our advice to University of Pittsburgh or Notre Dame fans who plan to attend tonight's football game at Heinz Field.

By mid-afternoon today, traffic was in gridlock around the stadium and had backed up on roads and highways leading to the North Shore. Parking lots already were filled or filling up,and ticket scalpers were out in abundance, hawking wares at prices "cheaper than $100."

Students, too, have swarmed to the North Side and have lined the sidewalks leading to the stadium's gates. Some are sleeping on the sidewalks, where they've apparently camped for some time to avoid that last-minute rush.

Kickoff is at 8 p.m.
