Minnesota has one near the airport (http://www.dot.state.mn.us/funding/projects/bloomington.html http://www.dot.state.mn.us/funding/projects/bloomington.html) that also has a light rail line running through it. It seems to work well but is definitely a little alarming the first time you drive through it.
