Interstate 465 (
I-465), also known as the
USS Indianapolis Memorial Highway, 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 leg 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 was completed in the fall of 2012 to refurbish the western edge of the loop.
