I-675/Grange Hall Road Interchange Project
The proposed I-675/Grange Hall Road interchange project is in the planning stages of the modification of the I-675/Grange Hall Road interchange to upgrade the existing interchange from a partial interchange to a full interchange. Work associated with this portion of the project
includes a Conceptual Alternative Study (CAS) and Interchange Modification Study (IMS), along with supplemental research and documents, for the planning portion of this modification.

The purpose of the I-675/Grange Hall Interchange project is to improve travel efficiency and safety as well as better access to the two current major regional business/employee centers of WPAFB, Wright State University, and Soin Medical Center on Pentagon Blvd in the project area.
This project will modify the I-675/Grange Hall interchange to a full interchange that considers impacts on local businesses and the surrounding community to the degree consistent with the travel efficiency, system linkage goals, fiscal responsibility, and safety.
Measurements of success for this project will include the following: improved traffic efficiency, increased safety through crash reduction, decreased congestion, increased roadway Level of Service, improved access to regional employment centers (WPAFB, WSU, Soin Medical Center).
Within 0.5 miles of the proposed completed interchange is about 35 acres of vacant land, not including land within the fence at WPAFB. A full interchange near this location will accomplish many things that will make this an attractive area to build. Among the outcomes will be easier
access for users coming from US 35 that don't want to compete with base gate traffic, an ease of congestion at the light on Col. Glenn Hwy/I-675 off ramp, and increased access for those living in the numerous homes/apartments/condos just to the south and southeast of the proposed
interchange. This again, will make the vacant land more attractive for new businesses to build in the area, expanding their current operation. Based on developed land in the area, we would anticipate, on average 3,500 SF of retail/office/educational floor area per acre of new developed
