Paul Gruner, P.E., P.S., Montgomery County Engineer, announced today that West Alex Bell Road will be closed between Mad River Road and McEwen Road for the major rehabilitation of the bridge over Holes Creek, and a detour will be in place. Construction is planned to start on Monday, August 24, 2020, with the closure starting immediately. The bridge is expected to be closed for approximately 120 days.
Through traffic will be required to take the detour, which will be clearly posted. This bridge is located immediately east of Mad River Road. The detour eastbound will be Mad River Road south to Yankee Street to Miamisburg-Centerville Road (SR 725) to McEwen Road back to Alex Bell Road. Westbound will be the reverse. Local traffic only will be maintained west from McEwen Road to the bridge site.
The existing bridge carries approximately 10,000 vehicles a day. The bridge superstructure, made up of prestressed concrete box beams, has deteriorated rapidly over the past several years. As a result, the condition rating is 4 (poor) out of 9, and the sufficiency rating is 21 out of 100. It is classified as structurally deficient and is posted with a load limit of 15 tons for a 2-axle truck and 20 tons for a semi-truck.
The project will replace the existing prestressed concrete box beams with new and add a concrete deck. The bridge deck width will remain at 32 feet, but the distance between bridge railings will increase from 30.8 feet to 32 feet. Minor repairs and patching of the abutments and piers will be necessary. Concrete approach slabs will be built on both sides of the bridge, and reconstruction of the pavement will occur to transition from existing pavement to approach slab. One driveway will be raised to provide better sight distance over the bridge railing. Eagle Bridge Co. of Sidney, Ohio was the successful low bidder at $731,124.70 and will be constructing the project. Funding was obtained from the Ohio Public Works Commission for the entire cost of construction of the project.
The patience of the public, their following of the posted detours, and their careful, safe driving during this period is greatly appreciated.
