Millikin Way Interchange

The Millikin Way Interchange will open more than 700 acres in Liberty Township for commercial development along the I-75 corridor. The proposed interchange is a critical strategy to support the community's growth and encourage economic development within Liberty Township. The goal of the interchange is to alleviate traffic congestion as the community grows, improve safety, support development, increase job opportunities and diversify the community's tax base.

In 2009, the Ohio Department of Transportation (ODOT) District 8 confirmed there is adequate spacing (more than 2 miles) between adjacent interchanges at Liberty Way (south) and State Route 63 (north). Since then, Millikin Way Interchange has been added to two important regional planning documents. 

Why Millikin?

  • The Millikin Way Interchange area is an important and growing corridor for public travel, commerce, and development in southwest Ohio. It provides regional connectivity across I-75 between Butler and Warren Counties.
  • With only 18% of land in Liberty Township designated for commercial development, encouraging development along existing transportation corridors like I-75, SR 747, and SR 4 is logical. 
  • The land planned for commercial development along I-75 will be difficult to achieve without significantly improving access to it. The local road network is limited and an interchange at I-75 and Millikin is necessary in order to open the land for commercial development.
  • The population growth in the Millikin Way Interchange area has contributed to significant residential and commercial development in Liberty Township and in the surrounding areas of Monroe, Deerfield, and Turtlecreek townships. Proposed improvements at I-75 & Millikin Road will improve access for drivers along local roadways in this area.

Your feedback is important to us


Public involvement is an integral component of our planning process. Public feedback is solicited and considered throughout each phase of the PDP. We expect to have a public meeting that will be conducted in accordance with local requirements for public gatherings early next year, but your feedback on our work is always appreciated.

If you have any comments, concerns or questions, please feel free to contact the project manager for the current interchange study:

Background and Process

Liberty Township has been one of the fastest growing communities in southwest Ohio over the past 20 years, with a 400% population increase from 1990 to 2010 (9,249 to 37,259 residents, respectively). Population is expected to continue to grow, with an anticipated population of 72,000 residents by 2035. This significant growth has contributed to ongoing residential and commercial development in the Township. As a result, local stakeholders have begun the process of exploring potential alternatives to alleviate traffic congestion, improve safety and support future investment and job creation,


Improved regional connections support our quality of life
Liberty Township is working with the Butler County Transportation Improvement District, the Ohio Department of Transportation (ODOT) and other local stakeholders to study a new interchange at I-75 and Millikin Road. This study process must follow the Project Development Process set forth by ODOT. The I-75/Millikin Road Interchange Study is in the second phase of this process. As part of our work, the project team is evaluating the traffic, environmental and property impacts of a proposed interchange as compared to the impacts of improving the local roadway network if no interchange is built.

Planned improvements will support future traffic and economic needs
The primary purpose of this potential project is to ensure that the local roadway network in Liberty Township is able to meet existing and future traffic demand and improve mobility and access to support planned community growth/development as identified in Liberty Township's Comprehensive Vision Plan. 

By the year 2044, the majority of the intersections within the study area of Butler Warren Road and Cincinnati Dayton Road, which currently serve as the primary north-south access routes, will be operating at what is considered Level of Service "F" during both the morning and afternoon peak hours.

Level of Service (LOS) "F" means that a given roadway can no longer meet the needs of the traffic using that roadway. Poor travel times and increased accidents generally characterize conditions when a roadway is classified at this level.

Similarly, intersections of Millikin Road, a major east-west corridor in Liberty Township, are also expected to operate at LOS "F" in 2044. Transportation improvements to address these congestion issues are needed too accommodate the projected traffic demand and improve mobility and access to support planned economic development in and around Liberty Township.
