My other secret (better for people going north) is to wait on the street on arch street next to the aviary. Then drive down the newly reopened merchant street underpass when the walkers near the red lot 7A and 7B on martingdale. Pick them up at this road or the light with reedsdale. Turn left on reedsdale. Go 1 block and follow the HOV lane for 279 north. And you’re whisked out of the north side. This could also work for OP but you’d want to them exit on Camp Horne road and take mount nebo road to 79 south heading for the airport

You can absolutely have him drive to walking distance to the stadium. And then wait in traffic for an hour like almost everyone else does. Know that this is the plan for thousands and thousands of people. But this is insanity. You can do better.

Please use our public transport. There’s a free newish subway station connected to the stadium. It will be filled with concert goers (not scary) and will have very frequent trains (beyond what online says) to pick them up when the concert ends.

This is the end of the line. So you can’t go the wrong way. Just get on a train!

If you’re going toward the airport, ride this train (for free) to the 1st avenue station. Have your husband wait on the street or in the parking garage near this station. When you arrive, turn left on grant street and follow the ramp for 376W. Within seconds you’ll be on 376W heading for the airport and will have to go through the fort Pitt tunnel, but will be coming from the opposite direction as everyone else and will be in the correct lanes for it without needing to merge. Should be almost no wait driving this route.

Or you could travel 2-4 more stops (beyond the free fare zone but who cares no one will notice in the concert crowd) and the subway will take its own tunnel and get you beyond the tunnel entirely. But this will probably take longer.
