PROJECT DESCRIPTIONDAR-SR721/SR722-05.43/05.54
PID 87382
The proposed project will rehabilitate the bridge on SR 721 over Harris Creek in AdamsTownship (Darke County)/Newberry Township (Miami County) and will replace the existingbridge on SR 722 over Stephens Ditch in Butler Township.
The project is funded with federal and state System Preservation Funds. The project is currentlyexpected to award in July 2014.
DAR-721-05.43 (SFN 1904264)
The existing 3-span bridge was constructed in 1965. It is concrete slab deck on capped pileconcrete abutments and piers. The clear spans are 24.25’-30’-24.25’. As of the most recentbridge inspection, the bridge had a general appraisal rating of 6(good) and a sufficiency rating of73.0. There is heavy deterioration of the deck edges resulting in the pavement sloughing offinside face of rail. The piers are cracked and there is minor rust and scaling. There are areas ofpunky concrete and heavy efflorescence on the abutment.
The bridge will be rehabilitated, deck edge repairs, abutment patching, and pier encasements. Theproposed maintenance activities are necessary to extend the life of the DAR-721-05.43 structure.
The proposed construction will be undertaken within the existing public right-of-way.
The project is located in a rural area with surrounding land in agricultural use or undevelopedwoodlot. OHPO GIS Mapping does not indicate any National Historic Landmarks, sites listed orknown eligible for the National Register of Historic Places, or sites for which OhioHistoric/Archaeological Inventory forms have been completed. This bridge has not beenincluded in the Ohio Historic Bridge Inventories.
Harris Creek is a modified warmwater habitat at the bridge location and is warmwaterimmediately downstream. The stream substrates are sand and gravel, with areas of heavy silt.No mussels or mussel shells were identified at the bridge location. Wetlands abut the streamthroughout most of the project work limits. There is an instream wetland upstream of the bridge;outside of the project construction limits. No trees are located within the proposed constructionlimits. The project is located within the designated special flood hazard area associated withHarris Creek.
DAR-722-05.54 (SFN 1904299)
The existing bridge was rehabilitated in 1960; the original construction is unknown. The bridge isa concrete slab deck on stone and concrete abutments. The bridge has a clear span of 18’and aroadway width of 29.5’. As of the most recent bridge inspection, the bridge had a generalappraisal rating of 5(fair) and a sufficiency rating of 84.3. While the bridge has an overallacceptable rating, there is considerable deterioration of the substructure, with cracked deterioratedstones and undermining and scouring of the abutments (with exposed footers). The deck hasspalling and exposed rebar.
The project is necessary to address the deteriorated condition of the abutments. Due to theextent of deterioration of the substructure, rehabilitation is not considered cost prudent.Replacements has been determined the more prudent alternative and will provide a structure witha lifespan of 50 to 75 years.
The bridge will be replaced with a 16’x 8’four-sided box.
Temporary right-of-way of up to 0.2-acre will be required for construction.
The DAR-722-05.54 structure is located in an agricultural area; all surrounding quadrants are incultivations. OHPO GIS Mapping does not indicate any National Historic Landmarks, sites listedor known eligible for the National Register of Historic Places, or sites for which OhioHistoric/Archaeological Inventory forms have been completed. This bridge has not beenincluded in the Ohio Historic Bridge Inventories.
Stephens Ditch is a tributary of Twin Creek with a drainage area of 3.4 square miles. StephensDitch does not have an assigned aquatic life use, but is tentatively classified as a warmwaterhabitat. No mussels or mussel shells were observed within the stream, which has a substrate offine sand and cobbles at the bridge location. No wetlands are present within the project limits.Trees within the project limits are narrow diameter scrub trees that do not offer habitat for theIndiana bat. The project is located within the designated special flood hazard area associated withStephens Ditch.
