Why it's listed

A white pine covered bridge with a Burr type arch spans Penns Creek about a mile west of Millmont in Union County, Pennsylvania. Dating from 1855, it has a span of 131 feet and a roadway 14 feet wide, and it has been restored several times, most recently in 1958. It connected a dirt road with a paved county road and served the lumbering and milling operations that increased population and commercial activity in the neighborhood in the early twentieth century. County commissioners kept the bridge rather than removing it, building a separate bridge one mile east instead. A weight limit of three tons was later imposed, and the bridge was closed to vehicles after a steel-concrete bridge opened nearby in 1976. Visitors can walk across the span and wade in the creek below. Its roof, sides, and masonry are described as in good repair, and the surrounding area is rural and wooded. It is regarded as an important surviving example of its type in the county.

Significance in brief: The nomination argues the bridge is significant as a surviving 1855 covered bridge and as a transportation resource tied to early twentieth-century lumbering and milling in the area. It is also described as significant for its engineering type, a white pine Burr arch. The form notes its continued use as a local historic site for school and tour trips.

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.
