Nearing the century mark, the Tunkhannock Viaduct still creates an impressive sight in northeastern Pennsylvania. Taking three years to build, the massive reinforced concrete bridge stretches out almost a half mile, used a whopping 169,000 cubic yards of concrete, and more than 1000 tons of steel. Its graceful central arches, spanning 180 feet, are supported by piers that were sunk 138 feet below ground level. Sitting on Tunkhannock Creek bedrock, its supporting piers took up almost half the concrete used on the project.
