The Pomeroy-Academia Covered Bridge in Port Royal, Juniata County is the longest remaining covered bridge in Pennsylvania.
The bridge was built in 1902 and is 278 feet long. It is a single-lane, double-span wooden covered bridge which crosses the Tuscarora Creek. Its design is based on the Burr truss developed by Theodore Burr, who was a preeminent bridge designer and builder. This bridge has been owned by the Juniata County Historical Societysince 1962. It was listed on the National Register of Historic Places in 1979.
Downstreem and off on the tributary Licking Creek, one finds the Lehman Covered Bridge, an historic covered bridge located near Port Royal in Juniata County. It is a Double Burr Arch truss bridge and was built in 1888. It measures 107 feet and has vertical siding, windows at eave level, and a gable roof. It was damaged during Hurricane Agnes in 1972, and subsequently rebuilt. It was listed on the National Register of Historic Places in 1979.
To the south is the Delville Covered Bridge. This bridge is located at Dellville, Perry County. It is a 174-foot-long, three span, Burr truss bridge over Sherman Creek, constructed in 1889. It was listed on the National Register of Historic Places in 1980. On November 3, 2014, the bridge was significantly damaged in a fire that police believe to have been caused by arson. By early 2019, most of the structure has been completely restored back to its original condition.
