Project Summary


The County Engineer is proposing to relieve congestion and improve safety at the intersection of Mad River Road and Alex Bell Road by eliminating the four-way stop and constructing a one-lane roundabout.  The project will build a roundabout with an outer diameter of 130 feet.   Pavement width in the roundabout will be 18 feet.  The center island will be landscaped with trees, shrubs, and flowers.  Construction is scheduled to begin in April of 2022 and last approximately four months.   The intersection must be closed to traffic during construction, and detours will be posted.

Should you have questions regarding the project, please contact Richard Splawinski of the Montgomery County Engineer’s Office at (937) 496-6510 or splawinskir@mcohio.org .
