After receiving grant funding, Delaware and Franklin counties plan to split the remaining cost of building a roundabout where four townships meet.

Delaware County commissioners Sept. 14 unanimously approved a cooperative agreement with Franklin County for work on a project to improve the intersection of Smothers and Red Bank roads. The intersection sits where the northern borders of Blendon and Plain townships meet the southern borders of Genoa and Harlem townships.

Rob Riley, Delaware County's chief deputy engineer, said Franklin County has agreed to oversee the design and construction of a new, single-lane roundabout at the intersection. He said Delaware County officials are comfortable with letting the neighboring county take the lead.

"They're capable and at this point we have about 40 other active projects, so we're happy to let them take this one," he said.

Riley said Franklin County has secured $1.3 million in grant funding from the Ohio Department of Transportation for the project. The two counties plan to split the remaining $1.1 million cost of the improvement.

Workers are expected to begin the anticipated three-month project to construct the roundabout in summer 2018.

Riley said the improvements are needed at the intersection just east of the Smothers Road bridge over Hoover Reservoir. Stop signs at the northern and southern legs currently control traffic at the crossroads.

"This will really address a problem intersection we both have," he said.

Delaware County Commissioner Barb Lewis, a former Genoa Township trustee, said she agrees the intersection needs improvement.

"Cars traveling to and from over Hoover Dam go very fast and it's a dangerous intersection," she said.

Riley said this is not the first time the two counties have collaborated on projects in the area. Delaware County oversaw efforts to install a roundabout at the nearby intersection of Harlem and Smothers roads a few years ago.

"We try to do our part when we can," he said.

The Smothers Road bridge over Hoover Reservoir reopened in July after Franklin County completed a $3.7 million repair project that closed the structure for several months.
