The portion of I-95 South between Westport and Greenwich is the busiest traffic corridor in the country, according to analytics company INRIX.

A survey found that taking the corridor every weekday during the 8 a.m. rush hour resulted in a driver losing 150 hours in traffic in 2024.

In 2023, the section of I-95 North from the Sherwood Island Connector to Exit 27 in Bridgeport was the third-busiest traffic corridor in the U.S, but it did not make the list this year.
