Minnesota has one near the airport (<a href="http:&#x2F;&#x2F;www.dot.state.mn.us&#x2F;funding&#x2F;projects&#x2F;bloomington.html" rel="nofollow">http:&#x2F;&#x2F;www.dot.state.mn.us&#x2F;funding&#x2F;projects&#x2F;bloomington.html</a>) 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.
