Wilmington/I-675 Improvement Plan

The I-675 and Wilmington Pike Interchange, a vital transportation hub serving Centerville, Sugarcreek Township, and Greene County, has become a cornerstone for the region's economic vitality. Connecting residents with major employers such as Wright-Patterson Air Force Base, Sinclair College, and Premier Health, as well as popular destinations like the Cornerstone Development shopping and entertainment district, this interchange plays an essential role in sustaining and expanding the local economy. However, growing traffic congestion in the area has brought forth the need for targeted infrastructure improvements to enhance safety, efficiency, and long-term accessibility.

In light of these challenges and opportunities, local government and planning experts are working to develop solutions that will meet not only today’s transportation demands but also support future growth and development. To ensure that these measures truly reflect the priorities and needs of those most impacted, input from residents, businesses, and community stakeholders will be at the forefront of this deliberative process. This project represents a critical chance for the public to shape the future of the region’s roadways and strengthen the area's capacity to thrive, and your feedback will directly inform the decision-making process.
