The MTA closed Montague for a year and the contractors tore out and rebuilt all the bench wall that was impacted, like 30K feet of it. In the Canarsie the MTA, or Cuomo rather, decided to only demo the worst parts and cover the rest.
Here is the new bench wall being installed in Montague:
This is what they're doing in the Canarsie instead:
Will there be problems in 5 or 10 years? Probably not. After that though I wouldn't care to place a wager. The Montague repair is certain to last many decades. |
The R train tubes will last 100 years that was a complete rebuild. Another Sandy like storm will most likely take out the L tunnel..
