The Metropolitan Transportation Authority, which operates the subway, had said the closing was necessary to fix damage from Hurricane Sandy in 2012, when the tunnel between Manhattan and Brooklyn was inundated by floodwaters.
The city had planned to close the tunnel, which runs between Brooklyn and Manhattan, for 15 months beginning in April to fix two tubes located beneath the East River.
The new plan no longer requires the two Brooklyn-Manhattan tunnels inside the line's superstorm Sandy-ravaged Canarsie Tube to close for the duration of the job. The technology, which was recommended by teams from Columbia and Cornell Universities' engineering schools, has not been used in the US.
Many L train riders were elated to learn the news Thursday.
Engineers say they will also be installing sensors inside the tunnels, so if there is any shifting in those power lines, they will immediately be alerted. He said not fully closing the L train would be a "phenomenal benefit to the people of New York City".
On Friday, according to NBC News, New York Gov. Andrew Cuomo said he'd asked Elon Musk's electric-car company to help brainstorm ways to improve the subway's signal system, which is one of the main issues being grappled with by subway overseer the Metropolitan Transportation Authority.
Hack exposes German politicians' data, but spares far-right party
ARD said that, after a first review of the data, journalists had not detected any incriminating content. The German Chancellor is the most prominent politician to have fallen victim of the cyber attack.
"It didn't feel very secure at all", she said.
"So long as this new strategy proves to be real, the mayor thinks this is great news for L-train riders", a spokesman for Mayor Bill de Blasio said.
"The governor's plan may or may not work, but you'll pardon transit riders for being skeptical that a last-minute Hail Mary idea cooked up over Christmas is better than what the MTA came up with over three years of extensive public input", said John Raskin, executive director of the Riders Alliance, a transit advocacy group. Since 1990, ridership has vastly increased, with about 400,000 rides on an average day.
Rather than the long-anticipated complete year-plus closure of the tunnel - which was expected to plunge cross-borough commutes into chaos starting April 27 - Cuomo backed a longer-term overhaul that would close one of the tunnel's two tubes at a time on nights and weekends, leaving the line fully operational during weekdays. Experts were projecting crippling congestion on the Williamsburg Bridge, and even more packed trains on the few other options for the North Brooklyn neighborhood.
MTA Acting Chairman Fernando Ferrer called the new plan "an innovative and more efficient approach" and said the agency, which operates in the city and its suburbs but is controlled by the governor, would adopt it in full.
