Worse place I ever stayed
There are 2 buses going to the downtown(G2, 28). And you'll need to cross a bridge by you own. In total it wouldn't take longer than 40-45 minutes. 10 minutes to the bus station, 20 minutes for bus ride, 10 minutes to cross a bridge.
I would say it's about 30min minimum from Heinz field. Taxi cabs would be the only mode of transportation from there.
