An additional three-mile section of Illinois 22 from Illinois 83 to Milwaukee Avenue, primarily located in Buffalo Grove, was another closely related project that was once again met with similar delays and concerns. Long Grove got on board in May 2005 and approved any widening between its eastern city limits and Illinois 83. Roadwork began in the fall on the two-year project, and in September 2007 it was finished; complete with four concrete lanes and a center grassy median. Again, intersection improvements were also made, this time adding dual left turn lanes to both east–west approaches at Illinois 83 and Buffalo Grove Road.
