WHY IS IT NAMED INTERSTATE 865?



Interstate 865 (I-865) is an east-west auxiliary Interstate Highway northwest of Indianapolis.

I-865 was originally part of I-465. The north-south section of the current I-465 between I-65 and the current I-865 was originally not part of I-465. That section of the highway was to be signed as Indiana State Road 100. However, seven months before the completion of SR-100, 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.

This 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 renaming of this branch of I-465 to I-865 fixed that problem.

At the time of the renaming, 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”.
