That's odd.
We rolled up around 5:00 for that game and drove right into the RedZone. Maybe consider looking for another route, 704 then cut up Belle Haven Dr and hang a left onto Sheriff Rd, then right onto Sean Taylor. That, or get there early.
It's not much better at other stadiums. My friends who park at the Ravens stadium say traffic getting out is a nightmare. It was a pain in the ass leaving the LInc after a MNF a few years ago. Same deal when we went to the Metallica concert at MetLife stadium a a few weeks ago.
Stadium traffic sucks, regardless of the venue. That's not on the owners.
The best thing to do is make a day of it., Get there early, tailgate, go to the game, and hang out for a little while after the game, while the traffic thins.
