Interstate 465 Indiana
Interstate 465 is a complete beltway encircling much of Indianapolis, Indiana. The freeway is mostly suburban, with major widening projects undertaken along the East Side in the late 90s and early 2000s and along the West Side (Accelerate465) between 2009-2012. With expansion up to eight lanes, reconstruction also modernized the freeway in both the Park 100 and the Allisonville / Castleton areas.
All U.S. highways and state roads were removed from surface streets within the Indianapolis Beltway over the course of the 1980s and 90s. This created a numbering headache as U.S. 31, 36, 40, 52, 421 and Indiana 37, 67, combine with the 53 mile long freeway loop at some point. Overlapped routes are generally not signed however, with signs solely referencing either I-465 or I-74/465 along the south side of Indianapolis. Guide signs and trailblazers reference the continuation of each respective U.S. route or state road at the Beltway entry points.

I-465 Annual Average Daily Traffic (AADT)
Interstate 465 superseded portions of Indiana State Road 100. SR 100 represented the original beltway along the East and West Sides of Indianapolis envisioned in the 1950s. Construction of the beltway began in 1959 and the first segment opened to traffic in 1961. The entire I-465 loop was completed by 1970.1
I-465 did not directly replace all of SR 100, as a portion of the route remains along Shadeland Avenue. The expressway branches north from I-465 at Exit 48 to Warren Park. This freeway was decommissioned as a state road in 1999.
Prior to 2002, Interstate 465 was also signed along the northwestern spur linking the Indianapolis Beltway at Zionsville with I-65 at Royalton. Locally known as the Dog Leg, this connector was renumbered as Interstate 865.
