这新闻讲错了
他不是整条地铁关闭，只是要整修河底隧道而已。
方案是这样的：
方案一 河底隧道段双线关闭18个月
所有L线车都改以Bedford Av.做总站，不驶入曼哈顿
配合整修，J与Z线车在Myrtle Av.与Marcy Av.拉下来做各停
方案二 河底隧道段以单线通行3年
L线会被切成两段
东线 Rockaway Parkway<>Lorimer St.
西线 第八大道-Bedford Avenue
另外西线不停第三大道站
J与Z线车拉下来各停的安排同上。

MTA Outlines Two Options for L Train Tunnel Closure
The Metropolitan Transportation Authority outlined two options for a looming
closure of the New York City subway’s L train tunnel, setting the stage for
a debate over how much pain riders will endure—and for how long.
One option calls for fully closing the L train’s East River tunnel for 18
months. This plan would sever a key link for Brooklyn riders, making it much
more difficult for patrons to get to dining and nightlife spots in trendy
neighborhoods such as Williamsburg.

It would also shutter a reliable crosstown subway route along 14th street in
Manhattan. That is because the L doesn’t intersect with other subway lines
in that borough, and a tunnel closure would prevent those trains from getting
to a rail yard in Brooklyn for repairs, inspections and maintenance.
A second option would keep one of the L train’s two tracks running under the
river but with infrequent—and likely crowded—subway service between both
boroughs. This repair plan would take three years.
The dual options were unveiled by MTA officials on Wednesday as they embark
on a public-relations campaign about the L train’s closure, which is
expected to begin in early 2019.
The tunnel overhaul is expected to cost an estimated $800 million to $1
billion, and officials compared its scope to repairs of damage the 1 subway
line sustained in the Sept. 11, 2001, World Trade Center terrorist attacks.
Nine of the subway system’s 14 underwater tunnels were damaged by superstorm
Sandy in 2012, but the L train tunnel suffered among the worst.
Repairs have long been expected to prove the most disruptive to New York City
’s transit network because the L is the only subway line between Manhattan
and northern Brooklyn, carrying an estimated 225,000 riders between the
boroughs each weekday.
“The L train is an important line to the people who ride it because there is
no substitute,” said Mitchell Moss, director of the Rudin Center for
Transportation at New York University. “It’s the coronary artery to
Williamsburg and the neighborhoods to the east.”
L Train Pain
The Metropolitan Transportation Authority unveiled options for closing the L
subway tunnel between Manhattan and Brooklyn starting in 2019. An estimated
225,000 riders pass through the tunnel each weekday.
OPTION 1
Two-track, 18-month closure
‧ No L trains between Eighth and Bedford avenues
‧ L operates between Rockaway Parkway
and Bedford Avenue
‧ J and Z trains make all stops
between Myrtle and Marcy avenues
OPTION 2
One-track, three-year closure
‧ No L trains between Lorimer Street and Bedford Avenue, free shuttle buses
provide alternate service
‧ L service operates in two sections:
1) Rockaway Parkway and Lorimer Street
2) Between Eighth and Bedford avenues
‧ L trains skip Third Avenue in both directions
‧ J and Z trains make all stops between
Myrtle and Marcy avenues.

The closure is part of an MTA plan to rehabilitate what is officially known
as the Canarsie Tunnel.
Built in 1924, the tunnel’s internal electrical systems and concrete innards
are deteriorating—damage hastened by lingering effects from corrosive
saltwater from superstorm Sandy, officials said.
While MTA officials say the L train tunnel is currently safe for trains
carrying passengers, they say they are trying to get ahead of problems that
could result in unplanned service disruptions—or worse.
Pointing to a collapsed concrete structure inside the tunnel, MTA officials
said a similar failure derailed a G train in Brooklyn last year, causing
minor injuries.
In detailing the two tunnel-closure options they are weighing, MTA officials
dismissed two other considerations.
Performing construction only on nights and weekends wouldn’t work because
potentially harmful silica dust generated by construction could extend
closures into the workweek, MTA officials said. Air tests and cleanup would
have to be completed before trains could resume running through the tunnel by
perhaps Tuesdays.
Digging another tunnel would also be a non-starter, said the officials, who
are worried about losing potentially hundreds of millions of dollars in
federal funding as the fourth anniversary of Sandy approaches and national
elections loom.
“That would take years and years,” said Ronnie Hakim, president of the MTA’
s New York City transit division, which operates the city’s subway and
buses. “We just don’t have the time to even undertake—even if we could
find the money—to do something like that.”
MTA officials are planning a public meeting in Brooklyn on Thursday; another
meeting in Manhattan is expected later this month. The goal is to let riders
and business owners weigh in on the closure options before the MTA’s board
votes on a repair plan later this year.

MTA officials sketched out early plans including beefed-up subway service
including on the G line, whose train length would double to eight cars.
There are plans for a shuttle bus to the J, M, Z lines to get riders over the
Williamsburg Bridge. MTA officials suggested a new ferry link to East 20th
Street in Manhattan, where riders could take increased express-bus service in
Manhattan.
“People are rightly desperate to preserve any service they can,” said state
Sen. Daniel Squadron, a Democrat whose district includes North Brooklyn and
who called for public MTA meetings about the tunnel closure. “But at the end
of the day it’s the best service that people are going to gravitate toward.”
L线过河隧道在珊蒂飓风受损最严重，但因为乘客过多一直没机会大检修...
话说在80年代，这条L线走的Canarsie Line差点要关门
因为乘客一天只有4万
现在与当年简直不可同日而语。
70 80年代的纽约地铁超恐怖的，涂鸦很多，犯罪频生，乘客大减。
反而亚洲国家的捷运系统都没这种问题。
顺带一提，L线的Canarsie Line可以在Broadway Junction汇入J/Z的Jamanica Line
不过可能因为路线容量与平面交叉等因素，没有实施直通运转。
纽约地铁非常的耐人寻味，历史古老
有很多路线，运转很复杂。
建筑结构许多都充满古代韵味，与亚洲的地铁截然不同。
