Why it's listed

A covered wooden bridge in Forks, Columbia County, Pennsylvania, the East Paden span measures 75 feet long and follows a Queen Post truss design, with two diagonal braces on either side of an iron tension bar. Its outer roof is metal sheeting, its underside is flat planks, and its portals are plain vertical boards. A continuous window runs along each wall. New flooring has been laid lengthwise through the bridge, and a horizontal steel beam reinforces the deck. The original abutments were kept, apart from a concrete wall added to connect the two bridges. Peter Ent is named as builder. The bridge is significant for its engineering and its place in local transportation. Covered bridges of this kind carried traffic between growing towns and the saw and grist mills that depended on farm trade. Columbia County has built none in the last half century, which makes these structures distinctive for their design.

Significance in brief: The nomination argues the bridge is significant for its engineering and its role in transportation. Covered bridges in Columbia County are described as having a unique design and engineering, since none have been built there in the last half century. Bridges of this type were needed to connect growing towns and the farming, saw and grist mill activities that depended on them.

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.

General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
