The next six spots in the top 10 go to Los Angeles roads.

“As for the bottlenecks themselves, the study’s top 50 list includes trouble spots in the following Metropolitan Areas: 12 in Los Angeles, 9 in and around New York City, 3 in Chicago, 3 near Washington DC, 3 in Houston, 3 in Boston, 3 in Dallas, 3 in Miami, 2 in Atlanta, 2 in Philadelphia, and 2 in San Francisco/Oakland.”

The study authors said they used the same data the Federal Highway Administration uses to identify routes where travel options need to improve.

After Chicago and LA, the next city on the list is New York City, with the 8th and 9th worst bottlenecks. Austin is No. 10 on the list.
