Project Overview

The I-71/75 & KY 338 Richwood Road Interchange Project is part of a comprehensive plan by the Kentucky Transportation Cabinet (KYTC) and Boone County to improve transportation service in the rapidly growing I-71/I-75 corridor.

Project History

The area surrounding the KY 338 (Richwood Road) interchange has experienced rapid development, leading to increased traffic on the local road network. Add to this the continued growth in traffic on I-75, one of the nation’s largest commercial routes, and you get traffic congestion and high accident rates. With this area expected to continue to grow over the next 20 years, so will the congestion and safety issues. More information on the project’s safety and congestion problems can be found in the Purpose and Need Statement.

In March 2010, KYTC published the Interchange Justification Study for I-71/I-75 at KY 536 and KY 338 (IJS), which evaluated a range of options to improve both the KY 338 (Richwood Road) and KY 536 (Mt. Zion Road) interchange areas. The primary recommendation of that study was to reconstruct each of these interchanges into a relatively new configuration called a double-crossover diamond interchange (DCD).

Study Area

Transportation systems function as networks. Problems (accidents and congestion, for example) can’t be analyzed and fixed, without considering the whole network. In the case of this project, because of the level of development along KY 338 and the close proximity of the I-71/75 interchange to Dixie Highway, KYTC is analyzing improvements over an area much larger than just the interchange as shown below. That’s doesn’t mean every roadway in this area will be improved, but all of them are being analyzed to see how they affect the network.

Project Status

Final design activity is ongoing. The design team is advancing the plan documents to a point where they will be ready when funding for right of way acquisition and utility relocations becomes available.

It should be noted the previous preconstruction and construction dates have been revised based on the new 2016-2018 Highway Plan approved by the General Assembly and Governor in April 2016. No funding is included in the current two-year biennium.  Funding for Right-of-Way relocations is currently shown becoming available in FY 2019.   Funding for utility relocations is shown for FY 2020.  Construction funding is shown in FY 2021 and 2022.

Changes can occur in the schedule as prioritization shifts or additional funding becomes available. In the interim, please continue to track this website for updates.
