The Kentucky Transportation Cabinet says the changes are in response to concerns from farmers that the current design could pose a risk to heavy equipment.
“The Cabinet has completed arrangements for the design changes,” said Kevin McClearn, Chief District Engineer for KYTC District 2, Madisonville. “Work has now started to remove all of the interior curbing so it can be replaced by a different curb designed to be more farm-tire friendly while still keeping the delineation. The new curb will help smooth the transition for any vehicle that may need to use it for extra space, such as heavy farm equipment that may move through the roundabout.”
The changes requested by farmers are expected to cost around 10% of the original cost, which was about $1.4 million. The main purpose of these roundabouts is to provide larger vehicles with more turning space. Farmers complained the current design would damage the tires of grain harvesting and other equipment.
“We checked with other state highway agencies that have constructed roundabouts where farm equipment travels on a regular basis. We did not get any reports of issues on roundabouts with similar curb designs. However, we chose to make some adjustments to accommodate concerns that were expressed,” McClearn said.
Work on the project should wrap up by the end of the year.
