Interstate 465 is the all-important freeway forming a full beltway around Indianapolis. It completely encircles Indianapolis, and INDOT loves to use that as a reason to absolve itself of any responsibility for any roadway mileage inside the ring drawn by Interstate 465. Any highway other than Interstate 65 and Interstate 70, that tries to reach Indianapolis, is routed around the city along Interstate 465 instead. For that reason, Interstate 465 is known to have the most routes concurrent along the same segment of highway. Eight different routes form concurrencies with Interstate 465, including Interstate 74, a mainline Interstate highway--and this isn't even counting the soon-completed Interstate 69. At one point on the east side of Indianapolis, Interstate 465 is concurrent with SEVEN other routes (US31, US36, US40, US52, US421, SR-37, and SR-67). Indiana won't even sign any of these concurrencies along Interstate 465, besides Interstate 74, because they know how stupid and confusing it would look.
In any case, if you're passing through Indianapolis getting from one locale to another, you're going to want to use Interstate 465. Interstates 65, 70, 74, and 69 form seven freeway alignments radiating in or out of Indianapolis (Interstate 69's southern extension is soon to form an eighth); to get from one to another, Interstate 465 forms an intermediate connection that's either handy or completely necessary. Interstate 865 helps access the northern leg of Interstate 65 toward Chicago, from points east on Interstate 465.
Interstate 465's exit numbers are numbered according to a convention respected for fully-formed circumferential Interstates. This convention puts mile zero at the southern junction with the mainline Interstate, and the numbers increase as the highway proceeds in a clockwise direction. (Interstate 275's mileages are also labeled in this way.) In Interstate 465's case, the first mile officially begins at Interstate 65's southern junction with the highway--it's also the fifty-third mile, since Interstate 465 is fifty-three miles long.
Interstate 465 officially begins at the southern junction of Interstate 65 on the southern side of Indianapolis. The first exit is labeled "53A" toward downtown, because Indiana decided it didn't want any exits numbered "zero"...
