Illinois 47 overlaps Illinois Route 72 and U.S. Route 20 at Pingree Grove, a village approximately 60mi from Chicago; this concurrency is part of a so-called wrong-way concurrency, where one can be driving both west on Illinois 72 and east on U.S. 20 at the same time.
In November 2013, a full access interchange opened at I-90 and Illinois 47.
