For many years, an interchange at the junction of I-57 with [[Interstate 294|I-294]] did not exist. It was one of the few places in the U.S. where Interstates cross but have no interchange. The [[Illinois Department of Transportation]] (IDOT) and [[Illinois State Toll Highway Authority]] (ISTHA) opened Phase&nbsp;1 of a new interchange in 2014, providing access from I-57 north to I-294 north and from I-294 south to I-57 south.<ref>{{cite news |last =  |date = October 25, 2014 |title = Interchange connecting I-57, I-294 opens |url = https://abc7chicago.com/interchange-opens/365814/ |access-date = March 14, 2022 |website = ABC7 Chicago |language = en |archive-date = March 14, 2022 |archive-url = https://web.archive.org/web/20220314201752/https://abc7chicago.com/interchange-opens/365814/ |url-status = live }}</ref> Phase&nbsp;2, which four of the remaining movements (northbound-to-southbound access being served by [[Interstate 80|I-80]]), was opened to traffic on September 11, 2022.<ref>{{cite web |title = I-294/I-57 Interchange Project - Phase 2 |url = https://www.illinoistollway.com/projects/tri-state/294-57-interchange |publisher = [[Illinois State Toll Highway Authority]] |access-date = December 3, 2022 |archive-date = November 4, 2022 |archive-url = https://web.archive.org/web/20221104135435/https://www.illinoistollway.com/projects/tri-state/294-57-interchange |url-status = live }}</ref>
