The I-270 Columbus North Central Outerbelt Study conducted in 2004 addressed capacity issues on the beltway between Sawmill Road (Exit 20) and Cleveland Avenue (Exit 27) on the north side of Columbus. The study outlined several options for improving the busy stretch of freeway, including interchange improvements at SR 315, U.S. 23 and Interstate 71.2
Work completed at the exchange between I-71 and I-270 replaced a loop ramp from the Beltway east to I-71 north with a new directional ramp and relocated the ramp to southbound. Just to the west along I-270 at U.S. 23, two loop ramps at the former full cloverleaf interchange were removed. Subsequent construction reconfigured the ramps with SR 315, added a single point urban interchange (SPUI) with Sawmill Road and converted the full cloverleaf at Cleveland Avenue into a six-ramp parclo.
