I had a similar question about a year ago with regards to Phoenix, Sky Harbor. The comments were all over the board but two comments were great, 1) use Google Maps and street view to do a virtual drive through and pay close attention to the clearance heights as you step through it and 2) call the airport and ask them.
I did both and determined that it would be no problem but I had to exit out the same way I came in. That's exactly what I did and it worked out fine.
The busses some people mentioned have proscribed routes and they know where not to go.
