It was built in 1902 by James M. Groninger.","why_significant":"The nomination argues the bridge is significant as an embodiment of a type of construction common during its period but now increasingly rare in the county. It is associated with the history of transportation in Pennsylvania and illustrates the technology of bridge construction in rural areas, as part of a group of covered bridges in Juniata and Snyder counties.","narrative":"Northwest of Spruce Hill in Juniata County, Pennsylvania, the Academia Pomeroy Covered Bridge crosses Tuscarora Creek. Built in 1902 by James M. Groninger, it is a Burr truss structure with two spans of 135 feet each, giving an end-to-end length of 270 feet, and a road surface about 15 feet 6 inches wide. It has vertical plank siding, open windows at eave level, a gable roof and cut stone abutments. Of the eight covered bridges in Juniata and Snyder counties, most use the Burr truss, a type favored for longer spans. The bridge is considered a surviving example of a construction type that was common in its period but is now increasingly rare locally. It is also associated with the development of transportation in rural Pennsylvania and illustrates how bridge networks were built in those counties. Its condition was recorded as excellent at the time of the survey.","period_of_significance":null,"architect_builder":"James M.
