Description
Philadelphia’s relationship with the underground is as old as the city itself, dating back to when Quaker settlers residedin caves alongside the Delaware River more than 300 years ago. Philadelphia later became a national and world leader in the delivery of water, gas, steam, and electricity during the Industrial Age. The construction of multiple subway lines within Center City took place during the early 20th century. An intricate subsurface pedestrian concourse was also developed throughout the downtown area for the city’s inhabitants. From 30th Street Station and Reading Terminal to the Commuter Rail Tunnel and transit lines that were never built, Philadelphia’s infrastructure history is buried under the earth as much as above.
