1. Los Angeles
Well, this is no surprise. If you've ever spent time in L.A., you know that it lives up to its reputation for having horrendous traffic problems. Inrix measured that the average Angeleno driver spent 64 hours in traffic last year. That's a five-hour increase from 2012 and the equivalent to eight full work days. There are many reasons for the congestion, not the least of which is the fact that Los Angeles is technically a county of 88 cities, which makes it hard to implement traffic strategies across all of the jurisdictions. The county has also been slow to open new freeways despite consistent population growth over the past two decades.
Worst Corridor: The I-405 SB between Roscoe Blvd to Mulholland Dr.
Worst Hour: Wednesday mornings at 8 a.m.
Travel Tip: The early bird gets the worm. The 405, sometimes nicknamed America's Worst Freeway, will always be busy on weekday mornings, but if you get on the road before 7 a.m., you have a shot a breezier ride.
