Henry Covered Bridge
Why it's listed
Near Monongahela in Washington County, Pennsylvania, the Henry Covered Bridge carries a road across Mingo Creek. It was built around 1881 and uses a queenpost truss, a simple form of timber framing in which two vertical posts support the roof-line of the truss. The bridge has vertical wood siding and a tin-covered gable roof, and its sidewalls are pierced by two square-cut windows. Its abutments are cut stone, braced with later concrete supports. The road surface is 12 feet 4 inches wide, and the end posts are 36 feet long. It was recorded in good condition when surveyed. The bridge was included in a group of covered bridges in Washington and Greene counties because it is a representative example of a once-common local wood bridge type. Few of these structures survive in the area, and the group together shows how a simple truss design was built across the two rural counties.
Significance in brief: The nomination treats it as an example of the local wood covered bridge type, which was once common and survives in comparatively high numbers in these two rural counties. The bridges in the group are said to show the type's construction technology and the simplicity of its truss forms, with some local design features. The document gives its listing as part of the group's thematic significance rather than a separate individual argument.

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.
