The bridge has a 136-foot end post length, an 8-foot 10-inch roadbed, and 12-foot 6-inch clearance. Its high exterior sidewalls leave narrow window rows under the eaves, and its portals have triangular edges. It can be seen from the Pennsylvania Turnpike. The property is significant as an example of wood bridge technology from the 19th and early 20th centuries, a bridge type once common in Bedford County. It is one of the county's surviving covered bridges, which were documented together as a thematic group.
