“The project is not to commence until mid-summer 2019 with completion nearly a year later in summer 2020,” Warren said.
ODOT District 8 spokesman Brian Cunningham said details are still being worked out on the final design, including acquiring right-of-way permits. Cunningham said the city has hired a design consultant, and ODOT will be responsible for the construction contract, project manager and inspectors.
Cunningham said “the two predominant factors” that are considered in whether to build a roundabout are reducing high-crash rates or alleviating congestion.

“We are seeing more of them because they do help traffic efficiency as well as safety,” he said. “They virtually eliminate angle crashes at intersections. We are seeing more and more of them because they work.”
Recent roundabouts installed in the area include two in Warren County at Township Line Road and Old State Route 122 and at Socialville Foster Road and Innovation Way Duke Boulevard near Kings Island.
Near Xenia in Beavercreek, three roundabouts have been installed — two on Park Overlook Drive and one on Idea Center Boulevard and Product Way.
Warren noted roundabouts are either present or being considered in “a growing number of Miami Valley communities including Troy, Urbana and Fairborn.”
He said in addition to improving safety, roundabouts “create attractive visual gateway entries to areas and neighborhoods.”

“The addition of a roundabout at Columbus and Church Streets in Xenia will ultimately reduce confusion and congestion at one of the more difficult navigational and heavily traveled intersections in the city,” he said, “all while bringing new landscaping and design to an area that (has) been long overdue for streetscape investment and improvement.”
