As part of the major project to upgrade 13 miles of US 31 in Hamilton County to a full Interstate-standard freeway, the I-465 north leg interchange at Meridian Street (exit 31) was reconfigured between October 2013 and December 2015 (with some additional work continuing until November 22, 2016) to the present partial directional (system interchange) design which allows for free-flow movements to or from the new US 31 freeway to the north.
