Also, I would try to time it so that you're not hitting St. Louis at rush hour. That city sucks to drive through IMO, but it's not so bad if you're off-peak.
Uh, no, not really.
Any major city will have traffic at rush hour, but it's better here than any other big city rush hour I've ever been in. In general, traffic here in STL is quite good.
Best traffic of top 20 metro areas
ETA -- Just checked more to make sure I'm not crazy. Despite being the 20th largest metro area in the US,
it ranks 79th in the US in traffic congestion.
And, the worst areas (270, in particular), is not what you're driving through.
Interesting call out, but not accurate. Drive freely!
