Why it's listed

Near Prosperity in Washington County, Pennsylvania, the Day Covered Bridge crosses Short Creek in Morris Township. It is a queenpost truss bridge with a 36-foot-6-inch span and a road surface 12 feet wide. Vertical wood siding encloses the structure, and a tin-covered gable roof shelters it. Its cut block abutments have been reinforced with concrete. The bridge is dated to about 1875. It is part of a group of covered bridges in Washington and Greene Counties documented together. Its significance lies in its representation of a once-common wood bridge type in Pennsylvania. The nomination treats the rural bridges of these two counties as examples of that construction technology, shown through their simple truss designs and local design features. The bridge was in good condition at the time of the survey.

Significance in brief: The nomination presents the bridge as an important example of vernacular wood truss technology, a bridge type once common in Pennsylvania. The document says the bridges of these two rural counties illustrate the type's construction technology and attest to the special character of rural county bridge building. The bridge's simplicity of truss design and local features of its design are cited as the basis for its significance.

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.
