freeway to the north. As part of its Operation Indy Commute project, INDOT began work in 2013 to widen I-65 on both its northbound and southbound mainlines from exit 103 at Southport Road northward to the junction with I-465's south leg, which would also be modified. To reduce congestion at and near that interchange, the loop ramp from westbound I-465 to southbound I-65 was replaced by a flyover ramp. The eastbound I-465 exit to southbound I-65 was also expanded for smoother merging with the new west-to-south flyover. In addition, grade separations over I-465 were replaced on Sherman Drive and Carson Avenue to allow for longer and wider approaches to this busy junction. Most of this work was completed in late 2014. Memorial designation Indianapolis native David Letterman had quintuple bypass surgery in 2000, and, two years later, suggested on his show that I-465 should be renamed the David Letterman Bypass, going so far as to call the mayor of Indianapolis during the Late Show with David Letterman. At the time of the gag on his show, Letterman had offered $10 million (equivalent to $ in ) for the honor, later offering just to pay to change the signs. In 2011 the Indiana General Assembly passed a resolution officially designating I-465 as "USS Indianapolis Memorial Highway" in "the memory of the brave sailors who lost their lives" when USS Indianapolis was sunk in the Pacific during World War II. Signs for this designation have been erected sporadically around the loop, but the highway is still referred to nearly exclusively as "I-465" or simply "465" by most locals. Future Upon completion of I-69 between Martinsville and I-465, I-69 will be signed concurrently on I-465 around its south and east legs in Indianapolis—between the new exit 5 for I-69 and SR 37 south on the southwest side and existing exit 37 for I-69 and SR 37 north in the northeast neighborhood of Castleton. Remaining sections of the I-465 beltway that are still awaiting reconstruction or widening projects include the west leg junction with I-65, the north leg between I-865 and US 31 north/Meridian Street, the north leg section from Allisonville Road to the I-69/Binford Boulevard interchange (with additional widening south to Fall Creek), and several portions along the south leg.
