這新聞講錯了
他不是整條地鐵關閉，只是要整修河底隧道而已。
方案是這樣的：
方案一 河底隧道段雙線關閉18個月
所有L線車都改以Bedford Av.做總站，不駛入曼哈頓
配合整修，J與Z線車在Myrtle Av.與Marcy Av.拉下來做各停
方案二 河底隧道段以單線通行3年
L線會被切成兩段
東線 Rockaway Parkway<>Lorimer St.
西線 第八大道-Bedford Avenue
另外西線不停第三大道站
J與Z線車拉下來各停的安排同上。

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線過河隧道在珊蒂颶風受損最嚴重，但因為乘客過多一直沒機會大檢修...
話說在80年代，這條L線走的Canarsie Line差點要關門
因為乘客一天只有4萬
現在與當年簡直不可同日而語。
70 80年代的紐約地鐵超恐怖的，塗鴉很多，犯罪頻生，乘客大減。
反而亞洲國家的捷運系統都沒這種問題。
順帶一提，L線的Canarsie Line可以在Broadway Junction匯入J/Z的Jamanica Line
不過可能因為路線容量與平面交叉等因素，沒有實施直通運轉。
紐約地鐵非常的耐人尋味，歷史古老
有很多路線，運轉很複雜。
建築結構許多都充滿古代韻味，與亞洲的地鐵截然不同。
