Work on the Montague tube, which connects Brooklyn and Manhattan under the East River, will likely begin in August and is expected to last 12 to 14 months, officials said.The Montague Street Tunnel serves the R train, and the MTA figures it will take about a year to do all the work.
The tube carries the R train, which takes tens of thousands of riders to Manhattan from southern Brooklyn.
An MTA official told the Wall Street Journal that lingering corrosion from the floodwaters is damaging equipment and wires, frequently causing system failures.
It will cost at least $100 million to replace the damaged parts in the Montague tunnel, the Wall Street Journal reported.
The alternative - shutdowns on nights/weekends, would have meant service disruptions and never being able to get ahead of all the problems.
This is expected to take about $100 million and 12-14 months. This particular tunnel was the hardest hit by Sandy, and took the longest to restore to service, but has been plagued with signal and electric power problems ever since.
The work involves:
Work includes the demolition of existing duct banks; removal & disposal of existing tunnel lighting, conduits, wiring, fixtures, ballast & receptacles; construction of new duct banks; installation of new Power & Communications cables in the new duct banks; reconstruction of circuit breaker houses CBH # 82, CBH # 83 & CBH # 91; rehabilitation of two substations (Montague Furman Substation & Broadway-Park Row Substation); new tunnel lighting including fixtures, wiring, & conduit; replacing isolation dampers & wiring for the fan plant; replacement of three submersible pumps & new AC/DC lighting at the pump rooms; track work including new rails & plates; installation of new 8" dry discharge line in both tubes; painting & lead abatement.The biggest problem is the one that isn't mentioned. Hardening against future storms isn't part of this plan. That means another Sandy-type storm would put the entire system back into a crisis with no option except to watch the system flood and pump it out and try to restore service.
That's not acceptable, but no one seems to have a way to find the funding to make that happen.
