Cosgray Road will close June 9 just north of Scioto Darby Road for approximately 60 days to allow for the replacement of the bridge over the Clover Groff ditch.
It will be a full closure and no through traffic of any kind will be permitted, said Letty Schamp, transportation engineer for Hilliard.
Direct access to properties south of the closure, including Darby Town Center and the CVS Pharmacy, will be accessible from the south only.
Access to locations north of the closure, including the YMCA, Homestead Park and residential areas, will be accessible from the north only.
The posted detour route for southbound traffic on Cosgray Road is east on Hayden Run Road, south on Leppert Road and west on Scioto Darby Road.
Northbound traffic south of the closure follows the same detour in the opposite directions.
The bridge replacement requiring the road closure is a joint project between Hilliard and the Franklin County Engineer's Office.
The project is estimated at $710,500 by the county engineer and is expected to be completed by the fall. Shelly and Sands is the general contractor.
The city will pay about $139,000 toward the construction cost, Service Director Butch Seidle said.
The Franklin County Engineer's Office will fund the remainder.
The city previously spent about $200,000 for the right-of-way acquisition and engineering required for the bridge replacement, Seidle said.
