The Atglen & Susquehanna in Conestoga TownshipDynamite was essential for expedient construction of the A&S. Rock cliffs on the Susquehanna River were blasted for months to create shelves that carried the rails northward, a lower route for the older Port Road and an upper route for the new A&S (lower right images). Both crossed the mouth of the Conestoga River at Safe Harbor on sweeping curves and new tandem bridges. Compressed air from a converted rolling mill in Safe Harbor was piped up the cliffs to drill pilot holes for filling with explosives. Boxed dynamite was passed by hand along the treacherous river face (upper right images). Hundreds of pilot holes were detonated simultaneously, debris removed, and the process repeated.
