Bridge in Franklin Township
Why it's listed
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.
Significance in brief: The nomination describes the bridge as a typical example of the open-spandrel concrete arch type, one of fifteen such arches built from 1906 to 1934 in the nominated group. 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.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
