History & local legend
The Delaware River Viaduct at Slateford was built between 1908 and 1911, using concrete supplied from plants on both banks. A cableway carried materials over the river, supported by a tower in midstream. Trains began crossing its nine spans in December 1911.
Its ghost story concerns a worker said to have fallen into a form during a concrete pour. According to the legend, his body remained inside the structure. Later accounts describe an apparition near the bridge and the sensation of being followed while crossing it.
