Interstate 865 Indiana


Interstate 865 is a short connector route between Interstate 65 and Interstate 465 northwest of Indianapolis, known locally as "the dogleg." This freeway provides a connection from Interstate 65 southbound to Interstate 465 eastbound and from Interstate 465 westbound to Interstate 65 northbound. The route was commissioned to alleviate confusion with having Interstate 465 radiate outwards in three different directions from one interchange.


The dogleg of 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 by November 5, 2002 when the Route Numbering subcommittee of AASHTO approved the creation of Interstate 865 between Interstate 65 at Royalton and Interstate 465 near Zionsville.

Planned Improvements

There are no interchanges on Interstate 865 at this time. However, there has been talk about adding an interchange at Copper Road.
