Dublin-Granville bridge replacement in New Albany will bring closures, but eventual shared-use path
A portion of East Dublin-Granville Road in New Albany is set to close July 13 through mid-November for a Franklin County bridge-replacement project.
Construction was set to begin this month but was postponed because of a delay in supplies due to the COVID-19 coronavirus pandemic, said Franklin County bridge-design engineer Edwin Herrick.
Franklin County is using contractor Shelly and Sands for the project, which has a bid estimate of $1.28 million, Herrick said. The completion of the project in mid-November is weather-dependent, he said. Dublin-Granville Road will be closed between Hamilton and Greensward roads, he said.
Bridges generally are designed to last 75 to 100 years, Herrick said, though a bridge's lifetime "really depends on the type of bridge" and many other factors. Franklin County inspects bridges annually, he said.
The Dublin-Granville Road bridge, which was built in 1951 by the Ohio Department of Transportation when Dublin-Granville Road was part of state Route 161, has deteriorated to the point of requiring replacement, he said.
The bridge, which crosses the Rocky Fork Creek, is 80 feet long, and the replacement will be 93 feet to improve water-flow capacity, he said. The bridge is 40 feet wide and will be widened by 7.5 feet to accommodate a shared-use path along the south side, he said.
The bridge will be built so that it potentially could accommodate a sidewalk along the north side, Herrick said.
The cities of New Albany and Columbus are contributing $95,000 apiece for the shared-use path, he said.
The current bridge doesn't have a shared-use path.
Because the county is building the bridge anyway, it made sense to build it wide enough for a path in case Columbus or New Albany installs paths near the bridge eventually, said city spokesman Scott McAfee. If such paths are built leading to it, the bridge already would have the space to add one, he said.
The posted detour route for motorists traveling east on Dublin-Granville Road will follow Hamilton Road north to state Route 161, east to New Albany Road, south to Fodor Road and south to Dublin-Granville Road. Westbound motorists will follow the detour route in the opposite direction.
