US-52 @ 65 Interchange Project

The Project known as US-52 @ 65, or the Lebanon Northern Interchange project will construct and realign US-52 to the north at a new interchange 3/10ths of a mile north of the CR 300N overpass on I-65 in Boone County. The interchange planned is a Crossover Diamond (also known as a Diverging Diamond) interchange.

Project Map and Description

New Interchange Selected Alternative

As seen in the interchange diagram, US-52 will curve eastward about 4/10ths of a mile west of CR 300N near Prairie Creek and continuing to a new interchange at I-65. The crossover diamond interchange design is the best alternative since it will help facilitate the movement of traffic onto and off of I-65 in both directions, as most traffic will not be through traffic. It also provides access to the new Eli Lilly development located to the northeast, as well as providing another alternative for a potential connection to SR-39 so that it can be relinquished through the city of Lebanon.

The ultimate routing east of a potential SR-39 connector has not yet been determined or released. New connecting roads and roundabouts have already been constructed or are under construction in conjunction with this project.

To the south, the existing US‑52 ramps will be fully removed, and the current alignment of Old US‑52 will be downgraded to a surface street. This roadway may also be reconfigured to serve as a connection to the planned LEAP District development located west of I‑65, which continues to expand as part of Indiana’s long‑term economic strategy. Old US-52 could also be reconfigured to serve as a gateway for the LEAP district (see below).

The LEAP District is envisioned as a major, long‑term economic development zone, most of which lies west of I‑65. The US‑52 @ I‑65 interchange project is being designed with that future growth in mind. As a part of this project, the old US‑52 roadway could be reconfigured to serve as a northern gateway to the Mixed-Use Village located in the heart of the LEAP District. LEAP which is short for Limitless Exploration Advanced Pace, is an advanced innovation district which will feature several advanced manufacturing companies and technology mega-sites along the SR-32 and US-52 corridors. The Eli Lily Manufacturing facility located northeast of the new interchange is part of this new district.

The new crossover diamond interchange at US‑52 and I‑65 is not only about improving interstate access—it also repositions the regional road network to support the LEAP District’s growth by providing mutiple access routes into the development. Additionally, this will provide improved North–South Mobility through the new multi-use village between SR-32 and US-52. This will provide a cleaner, more efficient link between Lebanon, the Eli Lilly development, and the LEAP District.
