Interstate 865 (I-865) is an east–west auxiliary Interstate Highway northwest of Indianapolis, Indiana. It is a short connector between I-65 and I-465, running for five miles (8.0 km) and completely concurrent with U.S. Route 52 (US 52). The highway was originally numbered as a branch of I-465 but was renumbered in 2002 to prevent I-465 from intersecting with itself. This section was previously known as the Dog Leg, and the mile markers ran from 900 to 905.
