Interstate 865 (abbreviated 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. I-865 is about 5 miles (8 km) in length.

[edit] Route description

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.

[edit] Interchanges

There are no intermediate interchanges on I-865.

[edit] History

I-865 was originally part of I-465. When the north-south section between I-65 and current I-865 was renamed from Indiana State Road 100 to I-465, an unusual T intersection of all three branches of I-465 resulted at the current junction of I-865 and I-465. The 2002 renaming of the west branch of I-465 to I-865 fixed this problem.

I-865 would more logically be named I-665, though officials decided against that as they figured it would be difficult for 9-1-1 operators to determine if a distressed motorist was saying "65" or "665".[1]

I-865 has no interchanges, other than its Eastern terminus at I-465 and its Western terminus at I-65. However, an interchange with Cooper Road may be built within the next few years.^{[citation needed]}
