Interstate 865 Indiana

History

Overview

Known locally as “the dogleg,” Interstate 865 is a short connector freeway northwest of Indianapolis between I-65 at Royalton and I-465 near Zionsville. The route was commissioned to alleviate confusion with having Interstate 465 radiate outwards in three different directions from one interchange.

There are no interchanges on Interstate 865, however, there was previous discussion about adding ramps at Copper Road.

History

The dogleg for I-465 was approved as an addition to Interstate 465 by AASHTO on June 30, 1970.

Signage for Interstate 865 was installed by May 2002. Approval from AASHTO came later at the Route Numbering subcommittee meeting on November 5, 2002.
