Chicago clings to a dubious distinction most drivers would rather relinquish.
For the fourth year in a row, Chicago was rated the third most congested city in the nation in 2010 by the INRIX National Traffic Scorecard.
The annual report also lists the Dan Ryan Expressway as having three of the worst bottlenecks, particularity at the Canalport exit according to the Chicago Sun-Times.
When is the worst time to be on the road?
Not that most Chicago drivers need to be told, but it's 5:15p.m. on Fridays when the average trip takes 41 percent longer.
Only New York and Los Angeles had worse overall congestion, with Washington, D.C., and Dallas rounding out the top five.
Traffic congestion is up almost 11 percent nationwide.
INRIX is a traffic and navigation service provider.
