Each manhole cover commemorates one of the 23 workers, almost all of them sandhogs, who have died thus far during the decades-long construction of Water Tunnel No. 3, the biggest public works project in the city's history. (There is a 24th death also associated with the project — a 12-year-old boy who fell down a 500-foot shaft while playing in a construction site.)

Water Tunnel No. 3 memorial

Amazing project. We flip a switch and expect power, turn a faucet and expect water but we don’t realize or appreciate what it takes for that to happen. Matt has a good appreciation. When looking out a window on a plane, I’m amazed that all those buildings on the ground are connected by pipes and wires.
