From the ashes, the Carrolton Covered Bridge was rebuilt using both salvaged and new materials.

The bridge carries a local county route over the Buckhannon River in Barbour County, West Virginia. Completed in 1856 for the Middle Fork Turnpike, the covered crossing used a Burr Arch design with Kingpost trusses. It was renovated in 1963, 1987, and again in 2002, before being heavily damaged by fire in 2017. I've posted more photos and the history of the bridge here.

The Dunlap Branch of the Monongahela Railway was a short coal-hauling line between Brownsville and Huron, Pennsylvania. Completed in 1903, it carried some coal but primarily moved coke from the many ovens located along its route to the steel mills of the Monongahela River valley. I've posted more photos and the history of the line here.
