Construction of a new bridge and associated road work will last until Nov. 12, the county said.
“The end of the bridge has been supported on temporary jacks for several years,” County Engineer Paul Gruner said in an email. “Drainage over the edge of the bridge also led to deterioration of the sides of the concrete slab. Repair was explored as a part of the design process, but repair costs were similar to full replacement.”
The project was awarded to Brumbaugh Construction, which bid $1.735 million, and engineering fees totaled more than $276,000, he added.
Slightly more than 19,000 vehicles on an average day use the bridge, which is posted for a 20-ton load limit, Gruner added.
“The bridge sits in neighboring Washington Twp., but many Miami Twp. residents use the route daily,” according to a post on Miami Twp.’s Facebook page.
The detour for westbound Lyons Road will be south along Yankee Street, west along Spring Valley Pike, and north along Washington Church Road, according to the county.
The detour for eastbound Lyons Road is north on Ohio 741, east on Ohio 725, and south along Yankee Street, officials said.
Businesses at the east end of the project — at the intersection of Lyons and Yankee — will be accessed from their Yankee Street entrances.
All other businesses along Lyons will be accessible from that road, according to the county.
An interactive map including detour routes and businesses in the area of the project is available at https://www.mcohio.org/government/elected_officials/engineer/projects.php. Periodic updates to the project will be available on the website as work on the bridge progresses, according to the county.
