That's horrible.One of the biggest expenses of building subway and commuter rail tunnels in western Queens is ground water mitigation. That's why MTA has to spend zillions building slurry walls everywhere. East Side Access is doing that. A nice chunk of the $645 million Connector project did that. Maybe the TA did NOT spend enough doing that when the original extension opened in 1989. I wonder if it's even possible to keep water out 100%. A lot of tunnels have small leaks in them all the time. You have to patrol them with maintenance crews, always plugging leaks when you find them. |
