This rural interchange is at the center of substantial local and regional economic development, and the current configuration does not meet the diverse needs of this thriving area. A new design is being developed to address capacity and safety concerns.

These improvements are possible thanks to significant investments and project development assistance from the City of Dublin, Union County, the Ohio Department of Transportation (ODOT) and the Mid-Ohio Regional Planning Commission (MORPC).

*This project is led by the Ohio Department of Transportation (ODOT). Questions concerning project development can be addressed to Matthew McGuire, ODOT D6 PIO, at 740.833.8222 or Matthew.McGuire@dot.ohio.gov. Details of this project can also be found on the ODOT webpage.
