In 2011, a 2.1 mile, $13.2 million project in Bannockburn and Highland Park got underway. It extended from east of I-94 to west of US-41, with the exception of the small section that was previously worked on in 2005. IL-22 was reconstructed and widened to four lanes with other smaller improvements along the way, including concrete pavement and dual left turn lanes at IL-43. The new lanes were initially opened by the end of 2012, with landscaping and finishing work carrying into 2013.
