Road Closure: Lamme Road Bridge Closure for Replacement in Miami Township

Paul Gruner, P.E., P.S., Montgomery County Engineer, announced today that Lamme Road will be closed to vehicular traffic at the bridge just north of Alex Bell Road for the total replacement of the bridge over Holes Creek. A detour will be posted for vehicular traffic, but pedestrian traffic will be maintained throughout construction. The road will be closed beginning on Monday, Jan. 23, 2023. It is anticipated that the bridge will be reopened to traffic no later than Oct. 31, 2023, weather permitting.

DETOURS:

Through vehicular traffic will be required to take detours, which will be clearly posted. The detour route for northbound traffic will be west on Alex Bell Road to State Route 741 (SR 741), north on SR 741 to Stroop Road and east on Stroop Road to Lamme Road. The detour for southbound traffic will be west on Stroop Road to SR 741, south on SR 741 to Alex Bell Road and east on Alex Bell Road to Lamme Road. The vehicular traffic detour map is attached to this notice. Pedestrian traffic will be maintained across the bridge at all times during construction. RTA Route 19 will be detoured but will still have a stop at Lamme Road and Bushwick Drive. A map ofthe RTA Route 19 changes is also attached to this notice.

THE PROJECT:

The existing bridge is a three-span, 155' long, 32' wide, prestressed concrete I-beam bridge built in 1957. It is the oldest prestressed concrete bridge in Montgomery County, along with a similar one on Diamond Mill Road. It is categorized as Structurally Deficient and Functionally Obsolete, and the structural condition is rated poor. It, therefore, requires total replacement. The new bridge will be a three-span, 187' long, 56' wide, structure composed of spread prestressed concrete box beams with a concrete slab. The width includes two 6' wide sidewalks. In addition to the new bridge, the project includes a new traffic signal at Lamme Road and Alex Bell Road with decorative mast arm poles with streetlights. In addition, the project will include curb and sidewalk repairs south of the bridge and resurfacing ofLamme Road north of Bushwick Drive. Montgomery County Environmental Services will be installing a new 30' water line from Alex Bell Road to 1,000' north of Bushwick Drive under a separate contract; the schedule will be closely coordinated with the bridge project.

The patience ofthe public, their following ofthe posted detours and their careful, safe driving and walking during this period are greatly appreciated.
