Bells Mills Covered Bridge

About Bells Mills Covered Bridge

Bells Mills Covered Bridge is a historic 95-foot Burr truss bridge spanning Sewickley Creek in southwestern Westmoreland County, Pennsylvania. Built in 1850, this beautifully preserved structure is the only surviving covered bridge in Westmoreland County, serving as the boundary line between Sewickley Township and South Huntingdon Township. Listed on the National Register of Historic Places in 1980, the bridge features distinctive Greek Revival architectural elements including pedimented gables and Tuscan piers at the portals, making it one of the more architecturally refined covered bridges in Pennsylvania.

History of Bells Mills Covered Bridge

Bells Mills Covered Bridge was designed and built in 1850 by Daniel McCain (1810-1891), one of the most accomplished bridge builders in western Pennsylvania. McCain served as superintendent of bridge construction in Allegheny County and built numerous notable bridges including the Ninth Street, Sixteenth Street, and 43rd Street bridges in Pittsburgh, as well as bridges for the Pennsylvania and West Penn railroads. At Bells Mills, McCain added arches to the multiple kingpost truss to create Theodore Burr's patented design, producing a longer and stronger bridge. The bridge takes its name from the Bell family who operated mills in the area. Despite bordering counties rich in covered bridges like Somerset, Indiana, and Washington, Westmoreland County's other covered bridges have been lost to time, making Bells Mills increasingly precious. The bridge was completely rebuilt in 1988 and repaired again in 2009 following a fire, demonstrating the community's commitment to preserving this historic structure.

Architecture and Design

The Bells Mills Covered Bridge showcases the Burr arch truss design, combining wooden arches with a multiple kingpost truss system. Modern engineers believe this combination keeps the slender Burr arches properly aligned and prevents them from buckling under load. The bridge measures 95 feet long and 14 feet wide, covered with a low-pitched gable roof. The exterior features horizontal clapboard painted in the traditional barn red color common throughout Pennsylvania, both inside and out. A cedar shake roof protects the structure, while the deck features lengthwise planking in wide tire track areas laid over crosswise planking. The Greek Revival architectural details set this bridge apart from typical covered bridges, with pedimented gables resembling ancient Greek temples and plain pilasters (flat columns) flanking the portals. Attractive picket fencing extends from either end of the bridge, adding to its refined appearance.

Visiting Bells Mills Covered Bridge

Bells Mills Covered Bridge is located near the small town of Yukon, Pennsylvania, approximately 3 miles from Interstate 70 and close to the Pennsylvania Turnpike. Despite its proximity to Pittsburgh and major highways, the area surrounding the bridge is surprisingly peaceful. A large pull-off on the western side of the bridge provides parking, though visitors should note that the bridge is surrounded by private property and a historic house sits adjacent to the structure. The bridge itself is public property and remains open to vehicle traffic for vehicles under 6 feet 6 inches tall. Visitors can also walk across to appreciate the craftsmanship up close. The bridge is approximately 40-45 minutes from Pittsburgh, making it an easy day trip. Nearby attractions include Cedar Creek Gorge, the Donora Smog Museum, and the breweries of the Laurel Highlands region. The historic Sewickley Presbyterian Church of 1831 stands nearby, along with a well-preserved five-bay brick house at 211 Bells Mills Road.
