The design principle behind the Burr arch truss is that the arch should be capable of bearing the entire load on the bridge while the truss keeps the bridge rigid. Even though the kingpost truss alone is capable of bearing a load, this was done because it is impossible to evenly balance a dynamic load crossing the bridge between the two parts. [5]
Theodore Burr (August 16, 1771 – November 22, 1822) was an inventor from Torrington, Connecticut, who was credited with the Burr Arch Truss bridge design. He designed and built one of the first bridges across the Hudson River and several bridges that crossed the Susquehanna River .
The bridge is covered by a metal roof, which extends on the east side over a walkway on the outside of the eastern truss. The bridge was built in 1833, and is at least the second-oldest covered bridge (after only the Pulp Mill Covered Bridge, which may have been built at a later date). It is also the state's longest single-span Burr truss ...
Landis Mill Covered Bridge was built in 1873 by Elias McMellen at a cost of $969. McMellen, who built many of Lancaster's covered bridges using the Burr arch truss, chose to build this short bridge using a simpler design with multiple kingpost trusses and, instead of Burr arches, pyramidal-shaped trusses to add additional support.

The bridge crossed Steel, Roberts, and Wood Islands. Construction of the bridge was started in 1817. [2] The bridge was constructed by Theodore Burr, who had just completed work on four Susquehanna bridges in Pennsylvania. The bridge design used his Burr arch truss. "This ultimate achievement of Burr's on the Susquehanna, having in all eighteen ...
The Kreidersville Covered Bridge crosses the Hokendauqua Creek. A Burr truss, wooden, covered bridge, it is 116 feet long, and is the last stop on the Lehigh Valley Covered Bridge tour through Northampton and Lehigh counties. [2] [3] The bridge was added to the National Register of Historic Places in 1980. [1]
The Leatherwood Station Covered Bridge is a single span double Burr Arch Truss covered bridge structure that was built by Joseph A. Britton & Son in 1899. Originally it had sandstone abutments but when it was moved to Billie Creek Village they were replaced with concrete abutments with sandstone showing. [4] [5]
The Bedell Bridge was a Burr truss covered bridge that spanned the Connecticut River between Newbury, Vermont and Haverhill, New Hampshire. Until its most recent destruction in 1979, it was, with a total length of 382 feet (116 m), the second-longest covered bridge in the United States .
