Montague Tubes Renewed
After Superstorm Sandy, the Montague Tubes were flooded to the ceiling with 27 million gallons of salt water. While temporary repairs allowed us to restore service as quickly as possible, the damage significantly reduced the lifespan of key infrastructure. During the 13-month closure of the tunnels, we performed essential repairs to restore, rebuild, and make the Montague Tubes less vulnerable to future severe weather events.
