A well-traveled route between the cities of Dublin and Powell will close for two weeks to allow workers to repair the bridge over the O'Shaughnessy Dam.

Columbus, which owns and maintains the Glick Road bridge, will close the span for resurfacing starting Monday, June 12. The city intends to re-open the bridge to traffic June 26.

John Ivanic, assistant director of Columbus' Department of Public Utilities, said the bridge has not been resurfaced since the early 1990s.

"Since then, we've done periodic patching and spot repairs," he said.

Ivanic said Columbus officials think the $561,000 project should prepare the structure for another 25 years of use by motorists.

"Now is the time to do a (resurfacing) project to avoid costly repairs in the future," he said.

Detour signs will be posted for the duration of the closure, but a dearth of nearby bridges could send drivers well out of their way to cross the Scioto River. The closest spans over the river are at Home Road -- about 3.5 miles north of the dam -- and Emerald Parkway -- about 3.5 miles south of the dam.

Ivanic said city officials hope the project will conclude within two weeks but said residents should check for updates on the work at pavingtheway.org.

Powell spokeswoman Megan Canavan said the city has posted information about the closure on its social-media accounts and website.

Although the work will occur west of city limits, Canavan said, it's important to reach Powell residents who could be affected by the project.

"We like to let people know about (closures) and give them a heads up," she said.

The work on the Glick Road bridge will start at the same time as another major road project just outside of the city.

The Ohio Department of Transportation plans to close state Route 315 between state Route 750 and Jewett Road for about two months starting Monday, June 12, for a project intended to stabilize the roadway's slope.

The O'Shaughnessy Dam, which is named for former Columbus waterworks superintendent Jerry O'Shaughnessy, was completed in 1925. O'Shaughnessy pushed for the creation of a reservoir northwest of Columbus near the borders of Concord and Liberty townships in Delaware County to meet the growing city's need for water.
