For all of you current, former, and wannabe Pittsburgh residents, I highly recommend checking out Pittsblog's "Welcome to Pittsburgh" series.
The author hits life in Pittsburgh right-on. I especially like the "Traffic and Roads" entry. I strongly advocate some of these environmental groups to run a campaign in the 'Burgh promoting constant speeds in the tunnel. Imagine how much gas and time is wasted every single day from people slowing down to 30 in the Squirrel Hill Tunnel. As soon as you get out of the tunnel (heading downtown), traffic moves like it was intended, which makes no sense considering that there are no merging lanes and just as many lanes coming out of the tunnel as there were going in.
I've done a fair amount of traveling and have never experienced a tunnel quite like the Squirrel Hill (except for maybe the Fort Pitt).
