Does the Metra train stop near there or do you have to walk or does a bus stop near it

What you can do is take the metro train downtown to Union Station when you get to Union Station and get out get out of Jackson Street and walk East as soon as you cross over Wacker you will see the Willis Tower's right on your left you can't miss it just look up you'll see it and it's very easy to get to and it's a great experience as I said once before when you ride in that are tunnel vacuum elevator Europe 1440 feet in 90 seconds it's a Thrill Ride
