LA's Forgotten Tunnel Systems Explained - 11 Miles Under the City (11x85)

:

The tunnels beneath Los Angeles, spanning over 11 miles, are a largely forgotten network that dates back to the early 20th century. Originally, some of these tunnels served as streetcar routes, connecting commuters across the growing city during the heyday of LA’s public transit system. Other tunnels were built to link civic buildings, facilitating the discreet movement of prisoners, officials, and even money between courthouses, jails, and banks. During Prohibition in the 1920s, these tunnels became infamous as secret passageways for bootleggers transporting illegal alcohol to speakeasies, with entrances hidden in bars and basements throughout downtown. While the tunnel network has since fallen into disuse, it remains a fascinating relic of Los Angeles’ layered history, hidden just below the bustling streets.
