Interstate 465 (I-465) is the beltway circling Indianapolis, Indiana, United States. It is roughly rectangular in shape and has a perimeter of approximately 53 miles (85 km). It lies almost completely within the boundaries of Marion County, except for two short sections on the north end in Boone and Hamilton Counties. It crosses I-65, I-69, I-70 and I-74, and provides additional access to I-65 via I-865. An $800 million project is underway to refurbish the western edge of the loop, with an estimated completion in 2014.[2]

Route description

Except for I-65 and I-70, no numbered highways run through downtown Indianapolis. All routes that continue from one side to the other run around the city, concurrent with I-465:

The approximately one-mile section between exits 46 and 47 carries eight routes — I-465, US 31, US 36, US 40, US 52, US 421, SR 37 and SR 67. It may also carry Interstate 69 in the future.

In most cases, markers other than I-74's are not posted along I-465 itself; rather, signs on onramps direct traffic following a particular route to follow I-465 to a particular exit to continue on that route.[5]

History

Much of I-465 replaced the routing of the defunct parallel State Road 100.

In 2002, the Interstate 865 designation was created from a portion of I-465 to eliminate the three-way intersection of I-465.

Also in 2002, Indianapolis native David Letterman's late-night talk show sidekick and band leader Paul Shaffer was honored by having a street in Thunder Bay, Ontario named for him. This led Letterman to ask (on his program) why he couldn't have his own eponymous road, and he suggested I-465 be named the David Letterman Expressway. His fans took the idea seriously, especially in the Indianapolis area where highway signs promoting the idea were displayed. Advertisers and traffic reports started to refer to I-465 as the "DLX", or later the "David Letterman Bypass", a reference to his quintuple heart bypass surgery in January 2000. Letterman even telephoned the Mayor of Indianapolis, Bart Peterson to make his case, but eventually the idea went nowhere.

In October 22, 2009, a liquid propane tank truck overturned and exploded on the ramp connecting eastbound I-465 to northbound I-69, damaging parts of the heavily-trafficked road in northeastern Indianapolis, including a bridge near the blaze.
