It is also noted as one of only four nominated concrete bridges in western Pennsylvania, and its significance is placed in the area of engineering.","narrative":"Built over Ten Mile Creek in Franklin Township, Greene County, this single-span concrete bridge carries vehicular traffic beside the Greene County Fairgrounds. Its open-spandrel arch measures 132 feet across the span, within the range of 40 to 200 feet found among the open-spandrel bridges in the group. The bridge was completed in 1919, according to a bridge plaque, and its design was credited to T. B. Dinsmore, a consulting engineer, with construction by Lippencott Brothers. A plaque on the structure names the county commissioners and engineer of the period. It is one of fifteen open-spandrel arches built in the region between 1906 and 1934. Its importance lies in its engineering: it is considered a typical example of the open-spandrel concrete arch type, and it is one of only four concrete bridges in the nominated group located in western Pennsylvania. The bridge is recorded as unaltered.","period_of_significance":null,"architect_builder":"T. B.
