$6.9 Billion Second Avenue Subway Phase II a "bargain"

Gov. Hochul sees light at end of NYC’s long-abandoned Second Ave. subway tunnel during tour with MTA chief
By Clayton Guse
November 23, 2021 7:42 PM



New York is about to build the world’s most expensive subway line — a project that’s been in the works for a century. Gov. Hochul on Tuesday toured a long-abandoned tunnel beneath Second Ave. in East Harlem that Metropolitan Transportation Authority officials plan to repurpose for the second phase of the Second Ave. subway.

The tunnel will help extend the Q line from its current northern terminus at Second Ave. and E. 96th St. to E. 125th St. and Lexington Ave. with two new stations in between.

The old tunnel runs between E. 110th St. and E. 120th St., and was dug in the early 1970s. Work stopped in 1974 amid the city’s financial crisis.

Extending the Second Ave. Subway 1.6 miles to Harlem will cost an estimated $6.3 billion, say MTA officials.

That’s $3.9 billion per mile, far and away the highest cost of any subway extension project in the history of the world, according to a study by researchers at New York University’s Marron Institute.

The price does not include the cost to use debt to finance the project, which brings the total bill to $6.9 billion.

The MTA has for more than two years awaited movement by the Federal Transit Administration to approve $3.4 billion to get the project going. Hochul on Tuesday said the money would come soon thanks to the infrastructure bill signed by President Biden earlier this month.

“We think we can get started one year from now,” Hochul said. Acting MTA chairman Janno Lieber said the sky-high price tag was a “bargain.”

“It will serve, when it opens, as many people as the entire Philadelphia subway system,” said Lieber.

“Everybody likes to talk about cost, but you’ve got to look at how many people it serves,” he said. “By the standards of riders, this is an incredibly efficient project, especially compared to everything else that comes before the federal government for funding.”

MTA filings to the feds estimate the construction of the extension will take seven years to finish. If that holds true, trains won’t run beneath Second Ave. in East Harlem until at least the end of 2029.

“I’m doing it in my terms in office, so it’s going to be a lot less than that,” Hochul said. She hopes the project will be speeded up by the controversial “design-build” contracting method the MTA has since 2019 been required by state law to employ.

Under design-build, the MTA consolidates design and construction work into a single contract rather than multiple separate contracts. Its impact on speeding up projects is not yet clear.

Hochul is the ninth governor to hold office since the East Harlem tunnel project broke ground during Nelson Rockefeller’s administration.

Plans to build the Second Ave. subway date back to the 1920s, when private companies ran the city’s subway lines. But it never came to fruition.

The abandoned tunnel Hochul toured is dusty, rusty and tattered — and it’s not the only one. The MTA in 1974 also stopped work on another Second Ave. tunnel between 99th and 105th Sts. that Lieber said will also be repurposed.

Another tunnel built by the city under Canal St. in Chinatown for the Second Ave. subway was also abandoned — but changes to the line’s plan mean it’s no longer needed.

The Second Ave. subway’s construction was approved in 1967 when New York voters OK’d $2.5 billion of bonds to pay for transportation improvements.

At the time, city and state officials planned for the line to run along Manhattan’s East Side up into the Bronx. If MTA officials ever make good plans for the line’s final two phases, the line would one day stretch from 125th St. to Hanover Square in the Financial District.

The money approved in 1967 was also supposed to pay for a set of double-decker East River tunnels, one of which now carries the F line between Manhattan and Queens. The other tunnel is being used for the MTA’s East Side Access project to bring Long Island Rail Road trains into a new station beneath Grand Central Terminal, which is expected to open to the public in Dec. 2022.

"A bargain" ? For the ultimate usage yes, but not in terms of construction costs. With 15 blocks already done, it is still ridiculous.

I really hope that's not going to be the case when they seriously start. Expanding Grand St from 2 to 4 tracks on the same level would be much more beneficial than splitting it between 2 levels. Then again, I probably won't be around when that happens.

Is it still supposed to go down Water Sreet ?
A few buildings along that street were built with basements that could accomodate entranes to it. What used to be called "88 Pine" was one of them. My mother worked there in the 1970's.

The tile work is not ostentatious. The size of the mezzanines, two of them at considerable depth, is some kind of display of grandeur, even if ostentation might be the wrong word.

LOL, the press gets it consistently wrong. They say the 1967 money was to be used for a pair of double-deck tunnels- no, just one. Which was built, but has yet to be fully utilized.

$750 million per station is a big deal.
So is spending $6.9 Billion for a subway that is half built.
Then taking 8 more years to get it done.

Most of that isn’t down to the station size and design but is a combination of high cost of construction in general and also graft and other factors that make construction in New York unnecessarily expensive.

They're pretty normal for modern underground stations all around the country. Only a guess, but it could be that modern safety and fire codes contribute to the need for larger stations by requiring quicker egress and for a way to evacuate smoke while still evacuating passengers.

The existing tunnels above 96th Street are much closer to the street surface because the topography changes. They won't need the long escalator/elevator runs to access the mezzanines.

I believe the 116 street station, which was not in the original SAS plans, will be built as an island platform in a section of tunnel that was originally designed to hold a layup track.

They are also closer to the surface as they were built using cut and cover and not deep boring. The 70s plan called for mostly cut and cover.

I think the tracks are remarkably level from 63rd street to 116th street - roughly at sea level, give or take a bit. At 63rd, 72nd, and 86th that's very deep and boring makes the most sense. At 96th and 106th that's pretty shallow, and so cut and cover makes the most sense.

Should we double the $7 billion estimate, and if so, can we still call it a bargain? Even $7 billion doesn't sound like such a bargain to me.

Not true.
That section of tunnel has Not been used as of yet.
Only as far as 99th st,or the end of new construction.

The tunnel IS CONNECTED TO THE NEW ROUTE for sure, but it's usage is limited to lay ups..the tunnel up to 105th st is trackless..only because they want room to work as far as the expansion is concerned.

It's graft. If they couldn't get the money, they would not charge it. London is 60% of NYC's cost and they have just as much garbage below the streets as we do from the 18th and 19th century version of those cities.

All the MTA has to do is dig the ENTIRE extension by mining. You take out the soil you need to remove with an elevator at the two stations. Work on both tunnel segments simultaneously from the beginning. Only remove the dirt you actually need to and see if you can co-locate more equipment at the buildings you have to condemn. The Army Corps of Engineers can build that tunnel for 1/2 price.

Frankly, the MTA's in-house construction teams do a good enough job that it may be wise to get them more involved in Capital Construction.

The soil composition of London is primarily clay, relatively easy to tunnel through (Roman ruins notwithstanding).

Manhattan, on the other hand, is primarily schist, very hard granite stone (although the East Side above 96th street is mostly former wetlands).

The segment from 116 Street to 125 Street will be the most challenging part to deal with. Still, I find it hard to believe that the total cost would be quite so high.

If the people that run this city had half of capitalist brain , they would have tried to see if any companies were interested in mining the schist . Yes , not a good solution for a project you are looking to complete fast but for how many facades has this project been stalled for . Even if the mta partially subsidized the operation .

Try googling the price of schist and do a calculation of the volume they could sell. Then compare against the cost of the project.
