Eckman, Sam, Covered Bridge No. 92
Why it's listed
The Sam Eckman Covered Bridge is a timber covered bridge near Millville in Columbia County, Pennsylvania. It measures 65.2 feet long with a roadway width of 14.5 feet and uses the Warren Truss design. The center section has diagonally crossed beams, with the upper half of a center post and an iron tension rod below. The undergirding is original, with no steel beams added. The roadway has a herringbone-pattern floor with two runways, and the walls are covered with board and batten. Joseph Redline is named as builder. One abutment retains its original stone and mortar, while the other was replaced with concrete. The bridge is significant for its engineering. Columbia County used several truss types, including King Post, Warren, Queen Post, Burr, and Howe, and the Warren Truss here is one of them. Bridges like this also connected growing towns with the farms and mills that drove local business, and the county has built no covered bridges in about half a century.
Significance in brief: The nomination argues the bridge is significant for its engineering as a Warren Truss covered bridge, one of the designs used in Columbia County. It also relates to transportation, since bridges were needed to link towns with farming and milling activities. The document notes that covered bridges have not been built in the county for about half a century, which it says makes their design and engineering unique.

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.
