Hayes Bridge
Why it's listed
Hayes Bridge crosses Buffalo Creek about two and a half miles west of Mifflinburg, Union County, Pennsylvania. Erected in 1882, it is a single-span King truss structure 63 feet long with a roadway 16 feet wide. The floors are white pine, and the bridge was repaired in 1957. Its carrying capacity has been limited to three tons. It is one of the few surviving covered bridges on Buffalo Creek, which once had at least ten, and one of five remaining in the county. Located on a dirt road, it carries little traffic today. Its importance rests on its transportation and engineering value as a surviving example of a local bridge type that has largely disappeared from the region.
Significance in brief: The nomination argues the bridge is significant as one of only two surviving covered bridges on Buffalo Creek, which had at least ten a century ago. It is one of five covered bridges remaining in Union County. The form marks transportation and engineering as areas of 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.
