Cosgray Road north of Scioto Darby Road is scheduled to reopen Sept. 5, almost three weeks later than originally planned, according to Hilliard Service Director Butch Seidle.
The section of Cosgray Road closed June 9 and was expected to reopen before the start of classes Aug. 19 for Hilliard City Schools, but wet weather delayed completion of a replacement bridge over Clover Groff Ditch.
Mayor Don Schonhardt said a wet summer raised the water table higher than expected and cause delays in the trenching needed to finish the bridge project.
"These were factors beyond our control," Schonhardt said.
The bridge replacement is a joint project between the city of Hilliard and the Franklin County Engineer's Office.
The city will pay about $139,000 for the construction cost of $710,500, Seidle said.
The Franklin County Engineer's Office is responsible for the rest.
The city previously spent about $200,000 for the right-of-way acquisition and engineering required for the bridge replacement, Seidle said.
