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.
