08/10/23 Roundabout update
The HAM-Plainfield Roundabout Project, consisting of three roundabouts in the busy Plainfield Road corridor in Blue Ash, is now complete!
While all three roundabouts are open, there will be some minor follow-up work at the Plainfield and Peppermill roundabout. Also, the Public Works and Parks Departments are working together to develop final landscaping plans for the construction area. This will include center island landscaping and stone veneers on the walls of the Plainfield and Peppermill roundabout.
The roundabouts were constructed to improve traffic flow, ease congestion, and increase safety for motorists and pedestrians. This was especially important at the Plainfield and Hunt intersection, which had been on the list of the most dangerous intersections in Ohio.
The total cost of the project from engineering to completion was approximately $15 million, with $11 million, or 73%, of the funding provided by federal grants. Construction began in September of 2021.
The City would like to thank you for your patience as the project was completed.

Once complete, these roundabouts will greatly improve safety and ease traffic congestion well into the future.
Thank you for your patience during construction.
(May 19, 2021 - Blue Ash)
The City of Blue Ash is about to begin construction of three roundabouts that will help improve safety and ease traffic congestion through the City.
At the May 13 City Council meeting, Council unanimously awarded the bid for the project, dubbed the HAM-Plainfield Road project, to R.B. Jergens Contractors, Inc.
Construction is expected to begin in the next few months.
Under the current plan, the roundabouts will be constructed in this order:
- Kroger entrance on Hunt Road
- Plainfield Road and Hunt Road
- Plainfield Road and Peppermill Lane
You may see work simultaneously at the different sites as crews prep the areas.
Currently, Duke Energy and other utility providers are in the process of relocating above-ground utilities at the intersection of Plainfield Road and Hunt Road to make way for the project.
During the next step of the project, crews will be demolishing the Speedway and Marathon gas stations at the corner of Plainfield and Hunt.
Traffic will be maintained during the construction process, though there may be lane closures from time to time. The only road closure is expected late this year and/or early next year when Peppermill Road will be shut down at Plainfield Road. Updates will be posted at blueash.com.
The total cost of the project from engineering to completion is approximately $15 million, with $11 million, or 73%, of the funding provided by federal grants.
Thank you for your patience as the City of Blue Ash completes this project. These roundabouts will greatly improve safety at these intersections and ease traffic congestion well into the future.
The roundabouts are scheduled to be completed in October of 2022.
