Tionti announced on September 12, 1967, that exit 166 would open once again after considering all the studies done on the interchange. Despite continued threats from Reid to close the interchange by force, Tionti noted that he would contact the mayor once a date was settled. Washington Township supported the decision, which would help at least 200 people from Washington Township to Park Ridge. The studies also suggested they should eliminate several left turns to help reduce the safety risk of exit 166, including trimming back trees to help visibility.
