 The final of the 17 segments of I-65 outside of I-465, from SR 252 near Edinburgh to Southport Road on Indy's far south side, opened on June 30, 1972.Unlike for most of portions of I-70 within the I-465 beltway, several inner sections of I-65 were built throughout the overall project lifespan.However, the final three segments from the south side through the heart of the city, including the common portion of I-65 and I-70 (east leg of the "Inner Belt"), were not finished and opened to traffic until around 1974.
