I-675 and Wilmington Pike Interchange Improvement
The Interstate 675 and Wilmington Pike interchange can be challenging to navigate. Increased traffic and congestion are resulting in travel delays and elevated crash rates. The City of Centerville along with Sugarcreek Township, the Greene County Engineer’s Office, and the Ohio Department of Transportation (ODOT) Districts 7 and 8 partnered to study the interchange and identified the following key contributing factors:
• There is traffic congestion along Wilmington Pike, including the I-675 interchange as well as the Wilmington Pike/Feedwire Road and the Wilmington Pike/ Clyo Road intersections
• Traffic exiting I-675 southbound onto Wilmington Pike extends onto the highway during the evening rush hour
• The traffic congestion and backups on the interstate contribute to the elevated crash rates in the project area
To address these issues effectively, the City of Centerville and its project partners have determined it is necessary to make improvements to reduce congestion and improve safety in the I-675 and Wilmington Pike interchange area. A Feasibility Study was prepared and public meetings were held in July 2023, which identified two viable options for improving congestion and safety: Alternative 1B (DDI/Diverging Diamond Interchange) and Alternative 2 (Split Interchange). An Alternative Evaluation Report (AER) was prepared to further evaluate the feasible alternatives and aid in the selection of a recommended preferred alternative. The AER identified that Alternative 1B meets the project purpose and need at a significantly lower cost than Alternative 2, therefore Alternative 1B DDI/Diverging Diamond Interchange is the recommended preferred alternative.
