Feel like traffic has been slowing down lately? You’re not the only one. According to the latest INRIX Gridlock Index (IGI) drivers across the U.S. spent more time stuck in traffic last June than they did in June 2012, with the national level of traffic congestion jumping by over 8 percent. Great news for economists and policymakers on the lookout for signs of an improving economy, but not so much fun for the rest of us.

June’s data also showed a big year-over-year rise in traffic for some of the nation’s largest metro areas. If you’re in Boston, you saw traffic jump by 28%, while in Philadelphia it rose by 25%. LA (12%) and San Francisco (14%) made the list of biggest risers as well (no surprise there, in car-mad California). What is surprising, however, is the news out of Detroit. While its recent bankruptcy filing leaves many to think the Motor City is out of gas, a reviving auto industry actually helped traffic to increase by 7% year-over-year.
