My neighborhood, Woodlawn in the Bronx, has strong working class roots, noticed by the presence of an AFL-CIO office and a bar named Aqueduct North, presumably after/for the workers who work on and in New York City's various water tunnels.
Sometime in the last two years, a memorial "for those who lost their lives in the construction of the Third Water Tunnel" was completed at Katonah Ave. & 241st Street. Done by New York City's Department of Environmental Protection (DEP), I think it's an appropriate and artistically interesting memorial. Below are a few photos.
There is also an annual memorial event honoring deceased water tunnel workers; I think it takes place in early spring. If I hear about it ahead of time, I'll post details. Please drop me an e-mail or comment if you hear info about a confirmed date.
The names on the manhole covers are a nice, simple touch.
