CHICAGO -- A new study released Monday by the American Highway Users Alliance identifies America's 50 worst bottlenecks and finds that the very worst bottleneck, as measured by hours of delay, is in Chicago.
The top-ranked Chicago chokepoint is located on the Kennedy Expressway (I-90) between the Circle Interchange (I-290) and Edens junction (I-94). The bottleneck was found to extend 12 miles, costing motorists 16.9 million hours' worth of time, equivalent to $418 million in 2014. More than 6.3 million gallons of fuel is wasted on I-90 while cars idle or crawl in traffic.
By just fixing America's worst bottleneck, an annual reduction of 133 million pounds of carbon dioxide emissions would also be likely, the study found.
Among the top 50 bottlenecks, there were two others in Chicago. Coming in at No. 23 on the list is I-90 between the Stevenson Expressway (I-55) and West Pershing Road. No. 46 is located on I-94 between the I-90 interchange
and North Elston Avenue.
