I'm guessing they probably got there before everything on top was built, but how do they get down there now for repairs and such?

- DanBC 14y agoThe water has to get in somewhere, and come out somewhere, so you go to those places and put a robot vehicle in.
- kibwen 14y agoFrom Wikipedia: "[New York City Water Tunnel No. 3] was authorized in 1954. A third tunnel was needed so tunnel one and tunnel two could be closed for repairs. Stage One was begun in 1970 and completed in 1993 and put into service in 1998."[1] This seems to imply that the later stages of the old two tunnels have never seen repairs.

- donohoe 14y agoNo - they're still building out these tunnels. My uncle worked briefly on the project in the 60's but its very much active http://www.youtube.com/watch?v=5gfSEjMtAoc http://www.youtube.com/watch?v=5gfSEjMtAoc
- pmb 14y agoThey don't. That's why they are building a third water tunnel. For backup, and so they can do repairs on the other two.
