2. There Are Hidden “Attic” Spaces at Each End of High Bridge
At either end of the bridge, there are attic spaces connected by a catwalk, where one can see the remnants of the Old Croton Aqueduct. The remains of the aqueduct system run along the underside of the bridge, according to Alyssa Loorya, President and Principal Investigator of Chrysalis Archaeological Consultants.
In the attic space on the Manhattan side, there is leftover graffiti from the Works Projects Administration era, a New Deal Agency which gave jobs to the unemployed to carry out public service projects.
