Manhattan Bridge in the Movies

This iconic image is from Sergio Leone's classic 1984 film "Once Upon A Time In America", which starred Robert DeNiro.

The view down Washington Street in Brooklyn's DUMBO remains largely unchanged to this day - minus the debris.

The Empire State Building is visible through the uprights of the bridge if you move slightly to your left in the street, and often the street is closed for film and music video shoots.

The Carroll Street Bridge

Only 2,018 more to go...

IMG_2063

The Carroll Street Bridge in Brooklyn is one of five bridges which span the Gowanus Canal. The canal has long been considered the dividing line between the Carroll Gardens and Park Slope neighborhoods although it is sometimes now referred to as it's own community - 'Gowanus'.

The five bridges are some of the most picturesque in the city and are, in order from North to South, The Union Street Bridge, The Carroll Street Bridge, The Third Street Bridge, The Ninth Street Bridge, and the Hamilton Avenue Drawbridge which runs parallel to the Gowanus Expressway at the mouth of the canal.

The Carroll Street Bridge was built in 1888 and is the oldest of only four retractile bridges in the United States. It rolls back horizontally on wheels set on steel rails in order to clear the waterway. The bridge was designated a NYC landmark in 1987.

View of the pulley and cable retraction system.

According to the EPA, the bridge was opened for water traffic 228 times in 1999 (the last year I could find available data.)

IMG_2075

The approach is still cobblestoned and the bridge itself is wooden planking. One of the better unnoticed details is the sign which remains atop the structure:

Opened to traffic: 1889

The Manhattan Bridge - Update

IMG_2094

Oooh - Sexy!

Yes, It's the bicycle specific, newly opened, bike lane on the Manhattan Bridge.
Check it out. Bike icons in both lanes.

Of course, I did see about 5 people on foot on the North Path, but who cares.

The approach on both sides is suicidal and takes you through some of the worst streets to cycle on, but it's so nice to ride across the river without fear of hitting or being hit by random tourists, kids, sightseers or joggers on the Brooklyn Bridge Footpath.

On the Manhattan side, the bike path entrance is at Chrystie Street on the left hand (North) side when facing the bridge from Canal Street.

The Brooklyn entrance to the path is a lovely new ramp at Jay and Sands Streets.
The approach to this is also crazy if you aren't used to riding in traffic - and hard to find if you don't know exactly where it is.

IMG_3331

The stairs to the pedestrian path are on the Jay Street side and the ramp is on the Sands Street side.

The intersection of Jay and Sands is right in the middle of the traffic pattern leading from the BQE to both the Brooklyn and Manhattan Bridges, so you need to be alert, but if you are coming from Downtown Brooklyn the Adams Street approach (AKA Brooklyn Bridge Blvd) is completely empty of car traffic.

The George Washington Bridge

Only 2,019 more to go...

IMG_2128

The George Washington Bridge seen from Washington Heights, looking across the Hudson River to the Englewood Cliffs.
Spans - New York-New Jersey, The Hudson River.

The George Washington Bridge is a toll suspension bridge spanning the Hudson River, connecting the Washington Heights neighborhood in the borough of Manhattan in New York City to Fort Lee in New Jersey by means of Interstate 95, U.S. Route 1/9. U.S. Route 46, which is entirely in New Jersey, ends halfway across the bridge at the state border. The GW is considered one of the world's busiest bridges in terms of vehicle traffic; In 2004, the bridge carried 108,404,000 vehicles, with current estimates of nearly 300,000 vehicles daily.
When it opened, the bridge had the longest main span in the world; at 1,067 m (3,500 ft), it nearly doubled the previous record of 564 m (1,850 ft), which had been held by the Ambassador Bridge.
The GW span is currently the fourth largest suspension bridge in the United States.

The bridge contains two levels, an upper level with four lanes in each direction and a lower level with three lanes in each direction, for a total of 14 lanes of travel. Additionally, the bridge houses a path on each side of the bridge for pedestrian traffic.

Groundbreaking for the new bridge began in October 1927. Its chief engineer was Othmar Ammann, with Cass Gilbert as architect. The bridge was dedicated on October 24, 1931, and opened to traffic the following day. Initially named the "Hudson River Bridge," the bridge is named in honor of George Washington, the first President of the United States. The Bridge is near the sites of Fort Washington (on the New York side) and Fort Lee (in New Jersey), which were fortified positions used by General Washington and his American forces in his unsuccessful attempt to deter the British occupation of New York City in 1776 during the American Revolutionary War.

Bridge facts from the wikipedia

IMG_2109


Modernist, Le Corbusier, said of the structure, "The George Washington Bridge over the Hudson is the most beautiful bridge in the world. Made of cables and steel beams, it gleams in the sky like a reversed arch. It is blessed. It is the only seat of grace in the disordered city. It is painted an aluminum color and, between water and sky, you see nothing but the bent cord supported by two steel towers. When your car moves up the ramp the two towers rise so high that it brings you happiness; their structure is so pure, so resolute, so regular that here, finally, steel architecture seems to laugh. The car reaches an unexpectedly wide apron; the second tower is very far away; innumerable vertical cables, gleaming against the sky, are suspended from the magisterial curve which swings down and then up. The rose-colored towers of New York appear, a vision whose harshness is mitigated by distance." (When the Cathedrals were White", 1947.)

IMG_2130

The bicycle and pedestrian pathway is accessible from 178th street, though the entrance to the ramp is so obscurely hidden that many people wander in circles, lost in the tangle of on-ramps and one-way streets.
The ramp itself is acutely curved and barely wide enough for two people, much less two cyclists. Once on the bridge, the pathway is fairly tight in places, narrowing through the towers into single lane, blind turns.
The path can be harrowing in high winds.


IMG_2099

The view from the center of the span is one of the most spectacular in the world.
Commanding a view of the lower Hudson, Manhattan, and the Palisades, it rewards those hardy souls who make the trip.
The bridge is a common starting place for cyclists who make their way up the NJ side of the Hudson for training rides.

Looking down and to the left, the 'Little Red Lighthouse' that used to guard ships from running aground on the rocky point is still holding vigil - although now dwarfed by the span above it.

The Upper Deck Approach from the Manhattan side.

Spans - Manhattan-Brooklyn, East River
Canal Street, Chinatown to Flatbush Avenue, Downtown Brooklyn.

The Manhattan Bridge was the last of the classic three East River Crossings to be completed. It opened to traffic on New Year's Eve of 1909, and has been plagued by structural issues almost from day one.
When fully utilized, the bridge has the capacity to carry four lanes of traffic on its upper level, three lanes of reversing traffic on its lower level, four subway tracks and two pedestrian pathways, one of which was earmarked as a bicycle only route.

I've never actually seen this, because the bridge has been under continuous renovation since before I can remember.

Rehabilitation of the Manhattan Bridge

"On Monday, August 6, 2007, the New York City Department of Transportation Division of Bridges will reopen the north bikeway of the Manhattan Bridge. The north bikeway has been closed since October 2006 to complete various construction tasks in association with the rehabilitation of the lower roadway of the bridge as well as to ensure and maintain public safety during the rehabilitation. Once the bikeway reopens the south walkway will revert to pedestrian use only."

The Triborough Bridge

Only 2,021 more to go...

IMG_1852.JPG

View of the pedestrian path on the East River section crossing from Astoria Queens to Randall's Island.

Spans Manhattan-Bronx-Queens, crossing Hell Gate (East River), The Harlem River, and the Bronx Kill.
The Triborough Bridge is a complex of three bridges connecting the three New York City boroughs of the Bronx, Manhattan, and Queens. The bridge uses what were originally two separate islands, Ward's Island and Randall's Island to support the center of the span.

The Robert Moses Building is the headquarters of M.T.A. Bridges and Tunnels, the successor to the old Triborough Bridge Authority. Robert Moses, the ultimate modern urban planner, kept his office at the center of his empire - on Randall's Island at the base of his biggest moneymaking bridge. Both the building and his office have been renovated over the years and no longer reflect the omnipotence of Moses at his peak.

IMG_1917.JPG

The Triborough does have a pedestrian path. It is mostly used by bicyclists who are legally required to dismount as they cross. Very few do so - until they run into one of the three staircases on the span. BEWARE.

For those of you who have never crossed the Triboro by bike or foot, it can be very confusing. The DOT provides this map, but I get confused all the time, so here's a simple explanation.

triboro path

There is no direct route for cyclists and pedestrians from Queens to Manhattan or the Bronx. Instead of following the traffic, the path drops you on Randall's Island from all directions.
You need to cross the island and find the correct span for the borough you are going to, making the bridge a two-step process.

I haven't actually taken the Manhattan entrance this year, so I can't vouch for it, but if the ramps are open, they're at 124/126th and Second Avenue. If not, the stairs are at 124/126th and First Avenue.
Alternately, there's the Ward's Island Bridge at 103rd Street and the FDR, which is for bicyclists and pedestrians only. Ward's Island connects to Randall's Island.

The Queens entrance is the stairs at 27th and Hoyt.

The Bronx entrance is the ramp structure at 133rd and Cypress.

The Verrazano - Narrows Bridge

Only 2,022 more to go...

IMG_2008

Spans - Brooklyn-Staten Island, The Narrows, New York Harbor.

According to the MTA, the Verrazano-Narrows Bridge was the world's longest suspension span when it opened in 1964.

"Its monumental 693 foot high towers are 1 5/8 inches farther apart at their tops than at their bases because the 4,260 foot distance between them made it necessary to compensate for the earth's curvature. Each tower weighs 27,000 tons and is held together with three million rivets and one million bolts. Seasonal contractions and expansions of the steel cables cause the double-decked roadway to be 12 feet lower in the summer than in the winter." (MTA website)

The Bridge at dawn as seen from the approach to New York Harbor

The bridge was designed by Othmar Ammann, who had also designed many of the most beautiful and iconic bridges in New York City, including the George Washington Bridge, the Bayonne Bridge, the Bronx Whitestone Bridge, the Triborough Bridge, Throgs Neck Bridge and the lovely, Hell Gate Bridge (AKA, The New York Connecting Railroad Bridge).
The dramatic silhouette of the span may be best known as the starting point for the annual NYC Marathon, but it is also featured in many films set in NYC. My personal favorite is from Saturday Night Fever when Tony Manero (John Travolta) and his Bay Ridge friends all get wasted and climb all over the cables.

The Macombs Dam Bridge

Only 2,023 more to go...

IMG_1978

Spans - Manhattan-Bronx, Harlem River.

The bridge and adjoining park were named for the Macomb family who operated a dam and mill on the site.
As use of the Harlem River increased in the 1830's, the dam, which blocked all but the smallest of boats became a local bone of contention. In 1838, a group of local citizens rammed the dam with a coal barge and destroyed it by chopping through it with axes.
In the course of the following lawsuit and court case, the dam was found to be "a public nuisance..." built "without authority of law...the Legislature did not authorize the obstruction of the navigation of the river in the manner in which it was done by the dam in question."

IMG_1981

After the Brooklyn and Washington Bridges, Macomb's Dam Bridge is the third oldest major bridge in New York City. It was designated a city landmark in 1992.
At the time of its construction, its massive steel central swing span was considered to be the world's heaviest movable mass.

This is more accurately the Harlem River Ship Channel as it is a man-made canal that was constructed in 1895.
The MTA, Marble Hill Station is in the foreground on the North side of the channel, the Circle Line is passing to the South, and the Henry Hudson Bridge is visible in the distance to the West.
Marble Hill is a truly strange example of NYC redistricting. The Harlem river originally passed to the North of the community, making it part of the island of Manhattan. When the channel was dug to facilitate the passing of larger ships, the area was cut off from the island, and the old river route filled in.
Marble Hill is still legally part of the borough of Manhattan.

The Brooklyn Bridge

2,026 to go...
Brooklyn Bridge & Woolworth B’... Digital ID: 800560. New York Public Library

No other bridge could be Number 1 on the list.

Span - Manhattan to Brooklyn across the East River

The Brooklyn Bridge, one of New York City’s most celebrated architectural wonders and arguably the most influential bridge in American history, was completed in 1883. Designed by John Augustus Roebling and completed by his son Washington Roebling, the Brooklyn Bridge was, at the time of its completion, the longest suspension bridge in the world, with a main span of 1595.5 feet.
It received landmark status in 1964 and is the oldest bridge that is open to passengers or vehicles.
The Brooklyn Bridge had 137,563 vehicle crossings on an average weekday in 2004.

Quoted from: Transportation Alternatives, The DOT, and
the Wikipedia entry for The Brooklyn Bridge

Pedestrian and Bicycle access to the Brooklyn Bridge -

Access to the bridge has improved markedly over the last few years.
The city recently added much needed signs and lighting to the Cadman Plaza Stairway entrance that is heavily used by tourists and pedestrians.
Last year, they added a two-way protected bike lane on Tillary Street to facilitate access to the bridge from the Downtown and Heights neighborhoods.
The Adams Street bike path is still basically unusable due to the fact that the Marriott allows livery cab drivers to park all along the length in front of the hotel.

The Manhattan entrance is easy to find, but hard to legally ride to on a bicycle. The safest thing to do is dismount and walk from the corner of Centre and Chambers Streets to the pedestrian entrance, due to traffic and crowds, but very few cyclists do this.

The pathway across the bridge is separated into two distinct lanes; the southern lane is for pedestrians, the northern lane for cyclists. These are clearly marked with icons, but are largely ignored by tourists who don't know any better.

Manhattan entrance: Park Row and Centre Street, across from City Hall Park.
Brooklyn entrance: Stairs under the overpass at Cadman Plaza East and Prospect Streets, or ramp to Tillary and Adams Streets.

Types of Bridges

According to most information out there on the internet, the majority of people group bridges into six main types:

Beam bridges - a rigid, horizontal structure that rests on two end supports. Beam bridges are the most basic of bridge design – like a log over a creek.

Cantilever bridges - a bridge built using cantilevers: structures that project horizontally into space, supported on only one end.
A simple cantilever span is formed by two arms that extend from opposite sides of the obstacle to be crossed and meet at the center.
The Queensboro Bridge is an example of a cantilever bridge.

Arch bridges - a bridge with abutments at each end shaped as a curved arch.
The Hell Gate Bridge is an example of an arch bridge.

Suspension bridges - Suspended from two high locations over a river or canyon, simple suspension bridges follow a shallow downward arc. Advances led to the development of the suspended-deck suspension bridge, a modern bridge capable of carrying vehicles and light rail. Instead of the deck following the downward arc of the main load-bearing cables (or chains), these cables are suspended between towers, and vertical suspender cables carry the weight of the deck below, upon which traffic crosses.
The Brooklyn Bridge is an example of a suspension bridge.

Cable-Stayed bridges - a bridge that consists of one or more columns (normally referred to as towers or pylons), with cables supporting the bridge deck. The cable-stay design is the optimum bridge for a span length between that of cantilever bridges and suspension bridges.
The East 153rd Street Bridge is an example of a cable-stayed bridge.

Truss bridges - a bridge composed of connected elements (typically straight) which may be stressed from tension, compression, or sometimes both in response to dynamic loads. This type of bridge structure has a fairly simple design and is particularly cheap to construct owing to its efficient use of materials. The truss may carry its roadbed on top, in the middle, or at the bottom of the truss.
The Kosciuszco Bridge is an example of a truss bridge.

Subgroups of these include:
Aqueduct, Causeway, Clapper, Compression Arch Suspended Deck,
Girder, Pontoon, Segmental, Side Spar, Trestle, Tubular, and Viaduct.

Moveable bridges are seen as a separate engineering idea, and include:
Drawbridge - the bridge deck is hinged on one end
Bascule bridge - a drawbridge hinged on pins with a counterweight to facilitate raising
Folding bridge - a drawbridge with multiple sections that collapse together horizontally
Curling bridge - a drawbridge with multiple sections that curl vertically
Lift bridge - the bridge deck is lifted up by counterweighted cables mounted on towers
Table bridge - a lift bridge with the lifting mechanism mounted underneath it
Retractable bridge (Thrust bridge) - the bridge deck is retracted to one side
Rolling bascule bridge - an unhinged drawbridge which is lifted by the rolling of a large gear segment along a horizontal rack
Submersible bridge - the bridge deck is lowered down into the water
Tilt bridge - the bridge deck, which is curved, is lifted up at an angle
Swing bridge - the bridge deck rotates around a fixed point, usually at the center, but may resemble a gate in its operation
Transporter bridge - a structure high above carries a suspended, ferry-like structure
Jetway - a passenger bridge to an airplane

Frequently Asked Questions

NYC Bridge Information from the DOT

Q: How many bridges are there in New York City? How many are under the jurisdiction of DOT?
A: There are 2,027 bridges in New York City. DOT's Division of Bridges is responsible for the design, construction, maintenance and operation of the 787 bridges (including 6 tunnels) and 67 culverts presently under the jurisdiction of the Department of Transportation.

Q: Who other than DOT operates bridges and tunnels in New York City?
A:MTA Bridges and Tunnels (formerly known as the Triborough Bridge and Tunnel Authority) operates the following structures: Bronx-Whitestone Bridge, Brooklyn-Battery Tunnel, Cross Bay Veterans Memorial Bridge, Henry Hudson Bridge, Marine Parkway-Gil Hodges Memorial Bridge, Queens Midtown Tunnel, Throgs Neck Bridge, Triborough Bridge, Verrazano-Narrows Bridge. The MetroNorth Railroad and the Long Island Railroad, both subsidiaries of the MTA, operate bridges and tunnels on their rail lines.

The Port Authority of New York and New Jersey operates the following bridges and tunnels: Bayonne Bridge, George Washington Bridge, Goethals Bridge, Holland Tunnel, Lincoln Tunnel, Outerbridge Crossing.

Q: Which bridge carries the largest amount of daily traffic?
A: The Queensboro Bridge. On an average weekday in 2004, some 180,369 vehicles crossed this celebrated cantilevered bridge between 59th Street in Manhattan and Long Island City in Queens. The Brooklyn Bridge had 137,563 vehicle crossings, the Williamsburg Bridge had 110,528 and the Manhattan Bridge had 79,129.

Q: How many New York City bridges are classified as historic landmarks?
A: As of January 1, 1998, ten bridges in New York City had been awarded some degree of landmark status. They include seven that are under the jurisdiction of the New York City Department of Transportation: the Brooklyn, Manhattan, Queensboro, Washington, University Heights, Carroll Street and Macombs Dam Bridges. The three landmarked bridges not operated by DOT are the George Washington Bridge (Port Authority of New York and New Jersey), Highbridge (NYC Department of Environmental Protection), and Hell Gate Bridge (Amtrak).

Q: What was the first bridge built in New York City? What is the oldest bridge still standing in New York City?
A: New York City’s first bridge, known as the King’s Bridge, was constructed in 1693. Fitted with stone abutments and a timber deck, it spanned Spuyten Duyvil Creek between Manhattan and the Bronx. It was demolished in 1917. The oldest bridge still standing in New York City is Highbridge, which spans the Harlem River between Manhattan and the Bronx; it was built in 1843. Highbridge is an aqueduct that carries a water main; it is not accessible to passengers or vehicles. The oldest bridge that is open to passengers or vehicles is the Brooklyn Bridge, which opened in 1883.

Q: When were the East River Bridges built? Which of the East River Bridges is the longest?
A: The four major bridges over the East River were constructed within four decades, from the start of construction on the Brooklyn Bridge in January 1870 to completion of the Manhattan Bridge in December 1909. The Brooklyn Bridge, one of New York City’s most celebrated architectural wonders and arguably the most influential bridge in American history, was completed in 1883. Designed by John Augustus Roebling and completed by his son Washington Roebling, the Brooklyn Bridge was, at the time of its completion, the longest suspension bridge in the world, with a main span of 1595.5 feet. The Williamsburg Bridge, with its 35-story steel towers, is the largest of the three suspension bridges that span the East River. When it was completed in 1903, it became the longest suspension bridge in the world, with a main span that is 1,600 feet long.
The two-decked Queensboro Bridge is one of the greatest cantilever bridges in the history of American bridge design. It was completed in March 1909. The last of the great bridges constructed across the East River, the Manhattan Bridge, opened on traffic on December 31, 1909.

Q: How many movable bridges does New York City operate?
A: There are 25 movable bridges in New York City, including two retractile bridges, seven swing bridges, four lift bridges, and twelve bascule (drawbridge) bridges.

Q: How many bridges connect Manhattan to other Boroughs or States?
A: There are 21 major bridges that connect to the island of Manhattan.
