The Jane Byrne Interchange (until 2014, Circle Interchange) is a major freeway interchange near downtown Chicago, Illinois. It is the junction between the Dan Ryan, Kennedy and Eisenhower Expressways (I-90/I-94 and I-290), and Ida B. Wells Drive.[1] In a dedication ceremony held on August 29, 2014, the interchange was renamed in honor of former Chicago mayor Jane M. Byrne (1979–1983).[2]
First developed in the late 1950s and 1960s, over time the interchange in its original configuration became notorious for traffic jams. In 2004, it was rated as the country's third-worst traffic bottleneck, with approximately 400,000 vehicles using it per day.[3][4] In a 2010 study of freight congestion (truck speed and travel time), the U.S. Department of Transportation ranked this section of I-290 as having the worst congestion in the United States.[5] This led to an $800 million reconfiguration begun in 2013 and completed in December 2022.[6]
