Come L or High Water: Sandy Damage Leaves MTA With Tough Choice




(WNYC) As subway-riding New Yorkers know, the system was dealt a huge blow during Sandy, when nine subway tunnels flooded with salt water.

"By far, the worst-damaged tunnel was Canarsie," said MTA president Tom Prendergast, naming the tunnel that carries the L train under the East River between Manhattan and Brooklyn. He said workers did what repairs they could, and flushed as much of the salt out as possible, in the days and weeks post-Sandy. "But salt remains, and so the corrosion continues. And there's a ticking clock with that."

Now, the MTA is preparing to make what it says are vital repairs: replacing the concrete that lines the cast-iron tunnel; rebuilding the concrete duct bank that runs alongside the tracks and carries electrical components, and installing new tracks and signals. (The MTA will also add entrances and elevators to the First Avenue and Bedford Avenue stations.) However, that requires the tunnel to shut down.

Here's where things get tricky.

Option A is designed to be a shorter, if sharper, shock: full closure of both tracks in the tunnel for eighteen months, beginning in January 2019. This accelerates the work — but limits the L train service to Brooklyn only. "That's sort of the mantra 'get in, get done, get out,'" said New York City Transit head Ronnie Hakim.



Option B preserves some service by keeping one track open. But "some" is the operative word here. Because of the need to single-track through the tunnel, "we'd reduce our service by about 80 percent," said Hakim. Meanwhile, the length of the work doubles...to three years.



Under each scenario, subway service on nearby lines like the A, C, G, J, and M would be increased, and the G would run full-length trains. The MTA would also run extra bus service over the Williamsburg Bridge, create shuttle bus service within Brooklyn to nearby subway stops, and consider new ferry service from North 7th Street to 20th Street in Manhattan. And once passengers get off the ferry at 20th Street, Hakim said, they'll be greeted by new Select Bus Service, the MTA's brand of bus rapid transit. "SBS on steroids," as she put it, "to bring people where they want to go." ....................(more)
