Thomas Covered Bridge
Why it's listed
Built in 1879 over Crooked Creek in Armstrong Township, Indiana County, Pennsylvania, the Thomas Covered Bridge is a wooden structure with a Town truss system and a total length of 52 feet between end posts. It has vertical siding, a gable roof, and an open window area at the roofline, and its floor is laid with boards running across the span. The bridge is one of four surviving covered bridges in Indiana County, which formerly had six. The other three surviving bridges are the Trusal, Harmon's, and Kintersburg bridges, and all four are owned by the county and kept in good condition. Together they form a thematic group that illustrates the county's nineteenth-century timber bridge construction. Its significance rests on its typical wooden truss construction and its place within this small surviving set of covered bridges in the county.
Significance in brief: The nomination argues the bridge is one of only four surviving covered bridges in Indiana County, a group that formerly numbered six. It is presented as a good example of wood-truss transportation technology within the county's covered bridge group, which is listed as a thematic resource.

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.
