Keller's Covered Bridge
Also known as: Guy Bard Covered Bridge

Why it's listed
A single-span wooden Burr arch-truss bridge crossing Cocalico Creek in Ephrata Township, Lancaster County, Pennsylvania. Lancaster County hired local contractor Elias McMellen to build it in 1872 for $2,075, and it was rebuilt by McMellen in 1891 for $1,250 after spring floods destroyed it. The bridge combines two long arches with a multiple king post truss, a design that was among the most popular vernacular bridge types in the eastern United States. Repairs in 1913 through 1918 used outside contractors, and vertical steel ties were added in 1935. Because the Rettew Mill Road site was to be replaced by a new bridge, the county agreed to move the covered bridge to Middle Creek Road, where it will cross Cocalico Creek on new stone abutments. The nomination treats its retained design and its link to Lancaster County's covered bridge building as the basis for its listing.
Significance in brief: The nomination argues the bridge is significant as a local example of the Burr arch-truss design, one of the most common covered wooden truss types in Pennsylvania and Lancaster County, and for its association with 19th-century bridge building in Lancaster County under contractor Elias McMellen. Its relocation was agreed as mitigation for an adverse effect from a replacement bridge project, and the nomination treats the move as keeping its eligibility.

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.
