Interstate 865 (I-865) is an east–west connector northwest of Indianapolis, Indiana. It was renamed to I-865 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.[1] It is concurrent with U.S. Route 52 for its entire route.

Route description[edit]

I-865 carries traffic from southbound I-65 to both directions of I-465, and traffic from both directions of I-465 to northbound I-65. No access is permitted from northbound I-65 to eastbound I-865, or westbound I-865 to southbound I-65. It has two lanes in each direction for its entire length.

History[edit]

I-865 was originally part of I-465. Original plans were for I-465 to run east from exit 129 of I-65 around the city to exit 123 of I-65. The north-south section between I-65 and the current I-865 was originally not part of I-465. Instead, it was built to interstate standards as Indiana State Road 100. In January 1970, seven months before it was completed, the federal government approved the request to make it part of I-465. This resulted in an unusual T intersection of all three branches of I-465 at the current junction of I-865 and I-465. The stretch of I-465 that is now I-865 was given mile markers starting with 900 to distinguish it from the main portion of the highway.[1]

The unusual configuration caused confusion among motorists, being described as "the 465 connector", "the 465 extension", "the 465 dogleg", "465 second section" and "the 465 ramp to 65 north." The May 2002 renaming of this branch of I-465 to I-865 fixed that problem.[1]

In naming it I-865 as opposed to I-665, officials concluded that 9-1-1 operators might have difficulty determining if a distressed motorist was saying "65" or "665".[1]

Exit list[edit]

I-865 only has interchanges at its eastern terminus at I-465 and its western terminus at I-65.[3] It is one of the few Interstates in the country that has only interchanges at each of its termini and none in between. Other examples include I-587, I-381, I-189, and the Portland, Maine iteration of I-495.

The entire route is in Boone County.
