The Highland Avenue portion of the road runs from the northernmost tip near Butterfield Road to 39th Street. From there to Pinewood Drive, the road maintains the name Main Street. South of there, the road's name becomes Lemont Road, as the real life road continues south through Darien, over the I-55 and to Lemont, Illinois.

This road is also known as DuPage County Route 9, from the northernmost edge to Ogden Ave, and starts up again at 55th Street. It is maintained by the county on these stretches.
