(July 13, 2021 - Blue Ash)

You will see an increase in activity as the HAM-Plainfield Roundabout Project ramps up in Blue Ash.

Several steps need to be completed before the road construction work begins in September.

Demolition of the Speedway and Marathon Gas stations at the corner of Plainfield Road and Hunt Road is expected to begin in late July/early August and should take several weeks to complete.

Lane closures and some night work will take place as Duke Energy gas pipeline work is completed on Hunt Road.

Cincinnati Bell is installing underground conduit in front of the Marathon Station and Evans Auto, then crews will install overhead cable on the new Duke Energy Utility poles along Hunt Road.

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

Once complete, these roundabouts will greatly improve safety and ease traffic congestion well into the future.

Thank you for your patience during construction.



HAM PLAINFIELD ROAD ROUNDABOUTS STEPS PNG
(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.
