Intersection closures in Orange and Berlin townships for roundabout construction will extend into August, according to Delaware County Engineer Chris Bauserman.
Construction of both roundabouts began in June.
Roundabouts at Lewis Center and North roads in Orange Township and Cheshire and Piatt roads in Berlin Township are nearing completion, Bauserman said, but both are in holding patterns awaiting the relocation of utility poles at both sites.
That relocation, he said, is the responsibility of the utility companies, not the road-construction crews.
"It's one of those things that's beyond our control," Bauserman said.
He said he expects the utility work at both sites to take three to four weeks.
American Electric Power spokesman Scott Blake said crews are working at both sites and could have new poles and electric lines finished as early as the end of this week.
Blake said other utilities are using poles at both sites and those lines would have to be moved to the new poles "before we can complete the removal on those old poles." He said he doesn't know how long that additional utility work would take.
After utility work is finished, Bauserman said, he estimates the Lewis Center/North work to last another two weeks; the Cheshire/Piatt work should be completed in less time, he said.
"It'll probably be late August, maybe early September" when the Lewis Center/North intersection reopens, Bauserman said.
After the Lewis Center/North roundabout opens, a third phase of work involving improvements to Lewis Center Road from the entrance to Olentangy High School, 675 Lewis Center Road, to Lewis Center United Methodist Church, 1081 Lewis Center Road, will require the road to be closed, according to Bauserman.
The roundabout includes prep work for a future, unscheduled connection to Green Meadows Drive to the south, he said.
The roundabouts are part of larger projects, according to the Delaware County engineer's website, engineer.co.delaware.oh.us.
The Lewis Center/North project's cost is $3.8 million, all paid for by Delaware County and Orange Township, the website says. The project began with the widening of North Road and includes the work on Lewis Center Road.
The Cheshire/Piatt project's cost is $4 million, including $490,000 in grant funds from the Ohio Public Works Commission, the website says. That includes the extension of Piatt Road north from Cheshire to Berlin Station Road, which already has been completed, as well as some paving work.
