About Adair's Covered Bridge

Adair's Covered Bridge, also known as Cisna Mill Covered Bridge, is a historic 150-foot Burr Arch Truss bridge spanning Sherman Creek in Perry County, Pennsylvania. Built in 1864 and later reinforced with steel I-beams in 1919, it is the oldest and second-longest covered bridge in the county. The bridge remains open to vehicle traffic and sits in a beautiful valley surrounded by farmland and forest.

History of Adair's Covered Bridge

Constructed in 1864, Adair's Covered Bridge is the oldest surviving covered bridge in Perry County. The bridge takes its name from the Adair family and is also known as Cisna Mill Covered Bridge due to its location near where Cisna Run enters Sherman Creek. The original structure was reinforced with steel I-beams in 1919 and underwent a complete restoration in 2007. It was listed on the National Register of Historic Places on August 25, 1980.

Architecture and Design

The bridge utilizes a Burr Arch Truss design, the most common style found in Pennsylvania covered bridges. At 150 feet long and 14 feet 3 inches wide, it features an interior height of 11 feet 4 inches. The planking consists of 3-inch boards laid crosswise. The bridge is painted in the traditional barn red color common to all Perry County covered bridges.
