NY's 16-Mile Car Tunnel Would Be Longest
By FRANK ELTMAN from Forbes

OYSTER BAY, N.Y. -

It would be the world's longest highway tunnel, running more than 16 miles under the west end of Long Island Sound.

The cost is estimated at $10 billion - and it wouldn't cost taxpayers a dime. A developer wants to build the tunnel with private money, recouping his costs by charging drivers $25 each way and by selling advertising.

Developer Vincent Polimeni says the tunnel between Oyster Bay and Rye on the New York mainland would let travelers going between Long Island and New England avoid crowded New York City highways and help alleviate traffic congestion.

While not expected to be completed before 2025, the proposal received renewed attention this past week when a state Senate committee held a hearing.

Polimeni acknowledges his idea was initially met with "smirks and skepticism." But he added: "The more people looked at the plan, the larger circle of intrigued citizens who said `tell me more.'"

The tunnel also brought back memories of Robert Moses, the powerful New York municipal planner who was rebuffed in his bid to build a bridge over Long Island Sound three decades ago. Long Island officials savaged Moses for his plan.

"Considering that we're on Long Island, I'm amazed they didn't run me out of the room," Polimeni, a developer of malls and office buildings in the New York area and in Poland, cracked during a recess at the hearing Thursday. "I think it's a good sign."

Oyster Bay Town Supervisor John Venditto described the project as "intriguing to say the least," but said his initial reaction was "it is unrealistic." He promised to review the data "so we don't have to make knee-jerk reactions and we can make an informed decision."

Elected officials from the proposed northern terminus were not as congenial.

"We cannot in Westchester (County) absorb the additional traffic that this tunnel would bring to our roads," said Rye Mayor Steven Otis. "It simply would make our roads nonfunctional."

He said the Westchester Municipal Officials Association voted in December to oppose the project.

Some Long Island residents agree with Otis' stand. Gino Longinotti of Syosset, just south of Oyster Bay, said he was curious about the project but didn't "see it being feasible. We have traffic conditions now where all the roads are congested."

Polimeni contends the estimated 80,000 vehicles a day using the tunnel would simply represent a shift in the roads being used, not an increase. He also argues the tunnel would ease air pollution because vehicles would be traveling shorter distances.

Polimeni has paid $250,000 out of his own pocket for engineering studies, and Bear, Stearns & Co. Inc. is providing investment banking advice.

Polimeni has also employed the engineering and construction firm Hatch Mott MacDonald, which has been involved in tunnel projects worldwide, including the 30-mile railroad "Chunnel" that connects Great Britain and France.

At 16 to 18 miles long, depending on the final design, the Long Island Sound project would eclipse Norway's 15.2-mile Laerdal Tunnel as the world's longest highway tunnel.

It would consist of two tubes carrying three lanes of traffic each, plus a central tunnel to be used for maintenance access and emergency ventilation and egress.

Where Moses - the man responsible for many of New York's major spans, including the Verrazano Narrows - failed in his bid to bridge the sound, Polimeni is not discouraged.

"Moses had the idea, only he was going to go up and over and nobody wanted to see this," he said.

The key to his strategy, is to take the project underground: "I thought, make it stealth."

I read this last month in Newsday and thought it was a pipedream, but now it seems to have some legs.

Wow, 16 miles. That would be incredible. It will be interesting to see how this progresses.

The Channel Tunnel (or "Chunnel") is actually made of three tunnels: two hold traffic and a smaller service tunnel serves as an emergency escape route.


The entire length of the Channel Tunnel is 32 miles (50 km), of which 25 miles (38 km) is underwater.


During construction, both Britain and France raced to see who would reach the midpoint first. Britain won.


It cost over $21 billion to complete the Channel Tunnel.


A road tunnel of even 16 miles brings lots more problems

The Laerdal Tunnel was built during a five-year period from 1995-2000. It is an important link in the ferry-free road connection between the Bergen area and Eastern Norway, including Oslo, and is especially significant for winter traffic, when the high mountain passes are closed, or subject to closing, because of snow.

This tunnel is not only the world's longest, 24.5 km, but also the world's most uniquely constructed tunnel with exceptional security features. An access tunnel of 2.1 km was built from a side valley, Tynjadalen, 6 km from the Laerdal side. This enabled the crews to drill from four sites, which shortened the construction time.

This access tunnel also serves as an extraction tunnel for the ventilation system, and made it possible to deposit the excavated rock on the Laerdal side in an environmentally secure area.

High air quality in the tunnel is achieved in two ways, by ventilation and purification. Large fans draw air in from both entrances, and polluted air is expelled through the ventilation tunnel to Tynjadalen. The Laerdal Tunnel is the first in the world to be equipped with an air treatment plant, located in a 100-meter cavern 9.5 km from Aurland, that removes both dust and nitrogen dioxide from the tunnel air. Two large fans draw air through the treatment plant, where dust and soot are removed by an electrostatic filter. Then the air is drawn through a large carbon filter which removes the nitrogen dioxide.

To support and strengthen the ceiling and the walls of the tunnel, 200,000 steel bolts of up to 5 meters in length have been used, and 35,000 square meters of concrete has been poured!

In order to break the monotony of a 20-minute drive, the tunnel has been divided up into four sections by creating three large caverns, or mountain halls, 6 km from each end and one in the middle. Special attention has been paid to the lighting. Whereas white light is used in the tunnel itself, the mountain halls are equipped with blue and yellow light. This gives one the illusion of driving into daylight every 6 km, and the golden light along the floor gives the illusion of sunrise! To keep the drivers from being inattentive or falling asleep, and thus causing head-on collisions, each lane is supplied with a loud rumble strip toward the center!

Asia's longest road tunnel opens

By Caroline Gluck
BBC, Taipei
Friday 16th July 2006

The longest underground road tunnel in Asia, and the 5th longest in the world, has opened to traffic in Taiwan.

The Hsuehshan, or Snow Mountain, tunnel is nearly 13km (8 miles) long and took nearly 14 years to complete.

A special commemoration service was held to unveil a memorial paying tribute to the 25 people who lost their lives during its construction.
The tunnel forms a key section of a new national expressway, which cost nearly $2bn.

The road connects the capital, Taipei, to the north-eastern county of Ilan and will cut journey times from more than two hours to just thirty minutes.

A key aim was to tackle unbalanced development. Ninety-five per cent of Taiwan's population live on the west coast, leaving people on the mountainous east coast complaining they were being overlooked.

"When this tunnel is opened to traffic, we expect to save about $450,000 a day in transportation costs," said Jun Da Jen, the project's chief engineer.

But building the system - which includes two primary tunnels and a network of interconnecting pedestrian and vehicle tubes - was almost "Mission Impossible."

The tunnel cuts through Taiwan's central mountain range and was plagued by problems because of the complex geology of the site. There were dozens of floods and collapses; many workers died; and some experts doubted it would ever be finished.

Now it is completed, officials in Ilan County are anticipating a tourism boom.
Land prices there have soared and dozens of new hotels are being built. More than 30,000 cars a day are expected to use the tunnel, with the figure expected to rise sharply at weekends.

I've lived in the Metro NY area all my life and after much reading of New York history, I find it hard to imagine what the area would be like if not for Robert Moses. Or what traffic would be like if he never got to complete his last couple of projects. The original plans for the bridge across the Sound were scrapped due to the same interferences that still reside in the L.I and Westchester,NY/Connecticut coastal communities. Instead, Staten Island got a bridge and L.I still suffers. The same NIMBY, sky-is-falling complainers are the ones who sit in traffic and complain about too many trucks. I really only see this tunnel helping commercial traffic.. namely trucks! It would take maybe a quarter of the trucks off of the L.I.E. the Throggs Neck Bridge and I95 North of the Bronx. It could have the potential of speeding up morning commutes to/from Manhattan.
I don't think it has a chance in hell of happening though. Especially not going through affluent communities which make up just about all coastal towns on both sides. Face it.. the last major road construction in the metro NY/NJ/L.I. area died with Moses. The only way anything will ever get done is if "we" the people stop complaining and accept that we have to sacrifice. You want to drive your car... well you have to have the new highway come through your town. I don't see any MAJOR capital road improvements (either government or private) happening until the local or federal government declares a national emergency and forces it down our throats.

Highway construction is something I have always been weary of. Although this may relieve the congestion of trucks on the LIE (which I can attest to first hand driving out to LI for 2 year period), I am weary it will help traffic at all. I mean once everyone else finds out that the highway is empty, all those who are not as fond of Public Transportation may jump on that highway, then you'll have congestion, but of another kind.

I'm not sure if I'd listen to their advice.

This link would be a wonderful thing. Instead of all of LI's traffic to the outside world having to go though NYC, the north and east traffic could go directly to I95 or I287. Also, in some sort of disaster, it would provide an evacuation route that didn't go through the city.

If the were going to build it, it would be silly not to include a rail component that could link the LIRR and Metro North.

Having a cross sound rail connection would indeed be fantastic.

I am not saying I am against the tunnel, just stating my fear as to what the outcome would be. Needless to say a rail connection is something that would definitely should be included, or else it is a wasted opportunity IMO.

Well, I personally wouldn't do the full length as a tunnel. I'd do a tunnel from the current end of NY 135, under the LI north shore (it being easier to tunnel under land than water). I would build an artificial penninsula attached to Bayville and bring the tunnel out there. From that point across the sound would be a causeway/bridge combo, into Rye, probably twinned with four lanes of traffic and two rail tracks a piece.

i live in the town right next to rye and i have to say id love to have this bridge/tunnel it would make traveling to long island where most of my friends live (being that i go to a SUNY school, everybodys from long island) a hell of a lot easier.

They should have built this back in the time of Moses. It would have been easier.
