'''Interstate&nbsp;865''' ('''I-865''') is an east–west [[List of auxiliary Interstate Highways|auxiliary Interstate Highway]] northwest of [[Indianapolis, Indiana]]. It is a short connector between [[Interstate 65 in Indiana|I-65]] and [[Interstate 465|I-465]], running for {{convert|5|mi|km|spell=in}} and completely [[concurrency (road)|concurrent]] with [[U.S. Route 52 in Indiana|U.S. Route&nbsp;52]] (US&nbsp;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.<ref name=indotpr/>

==Route description==

I-865 begins at an interchange with [[Interstate 65 in Indiana|I-65]] in the northwest outskirts of [[Indianapolis]], near [[Zionsville, Indiana|Zionsville]]. The interchange allows for traffic from southbound I-65 to continue east onto I-865 and connects traffic from westbound I-865 to northbound I-65 but prohibits other movements. [[U.S. Route 52 in Indiana|US&nbsp;52]] is concurrent with the entire length of the four-lane freeway as it travels east across several farms and suburban neighborhoods on the south side of Zionsville. After {{convert|4.7|mi|km}}, I-865 terminates at a three-way interchange with [[Interstate 465|I-465]], which continues around Indianapolis as a [[beltway]].<ref name="google">{{google maps |title=Interstate 865 |url=https://www.google.com/maps/dir/39.9364512,-86.3441694/39.9284181,-86.2624147/@39.9320778,-86.321051,6901m/am=t/data=!3m2!1e3!4b1!4m2!4m1!3e0 |accessdate=October 28, 2018}}</ref>

I-865 has interchanges only at its eastern terminus at I-465 and its western terminus at I-65.<ref>{{cite web |author= Indiana Department of Transportation |url= http://www.in.gov/indot/div/interchange/i-865.htm |work= INDOT Interchange Book |title=  I-865 |publisher= Indiana Department of Transportation |access-date=October 5, 2014}}</ref> It is one of the few Interstates that have interchanges only at their termini and none in between. Other examples include [[Interstate 587 (New York)|I-587]] in [[Kingston, New York]]; [[Interstate 381|I-381]] in [[Bristol, Virginia]]; the future [[Interstate 222|I-222]]; [[Falmouth Spur|I-495]] in Maine; and [[Interstate 189|I-189]] in [[Chittenden County, Vermont]].{{citation needed|date=October 2018}}

The highway is maintained by the [[Indiana Department of Transportation]] (INDOT). In 2022, INDOT measured [[annual average daily traffic]] on I-865 at 34,304&nbsp;vehicles.<ref>{{Cite web |date=2022 |title=Traffic Count Database System (TCDS): I-865 |url=https://indot.public.ms2soft.com/tcds/tsearch.asp?loc=Indot&mod=tcds&local_id=978980 |access-date=2022-12-21 |website=Indiana Department of Transportation}}</ref>

==History==

I-865 was originally part of [[Interstate 465|I-465]]. Original plans were for I-465 to run east from exit&nbsp;129 of [[Interstate 65 in Indiana|I-65]] around the city to exit&nbsp;123 of I-65. The north–south section of the current I-465 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|State Road&nbsp;100]] (SR&nbsp;100). In January&nbsp;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 [[Y interchange]] 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 milemarkers starting with 900 to distinguish it from the main portion of the highway.<ref name=indotpr/><ref>{{cite news |last=McFeely |first=Dan |date=April 24, 2002 |title=I-465 'ramp' renamed I-865 |page=A1 |work=The Indianapolis Star |url=https://www.newspapers.com/clip/74925358/i-465-ramp-renamed-i-865/ |via=Newspapers.com |accessdate=April 1, 2021}}</ref>

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 redesignation of this branch of I-465 to I-865 fixed that problem.<ref name=indotpr/><ref>{{cite news |last=McFeely |first=Dan |date=April 29, 2002 |title=I-865 name does follow protocol |page=B3 |work=The Indianapolis Star |url=https://www.newspapers.com/clip/24920939/i865_name_does_follow_protocol/ |via=Newspapers.com |access-date=October 28, 2018}}</ref> The renumbering was approved by the Special Committee on U.S. Route Numbering of the [[American Association of State Highway and Transportation Officials]] (AASHTO)  in October&nbsp;2002.<ref>{{AASHTO minutes |year=2002A |page=2 |link=yes |accessdate=October 28, 2018}}</ref>

At the time of the redesignation, officials chose "I-865" rather than the also available "I-665" because they concluded that [[9-1-1]] operators would more easily understand the combination of "8" and "65".<ref name=indotpr/>
