George Washington Bridge, New York City

The George Washington Bridge (George Washington Bridge, colloquially GWB, GW Bridge or GW for short) is a suspension bridge over the Hudson River in New York City that connects Manhattan to New Jersey. The road bridge with a total of fourteen lanes is considered the busiest bridge in the world. It is named after George Washington, the first President of the United States. When it opened in 1931, the bridge planned and built by Othmar Ammann had the longest span in the world.

 

Location

The George Washington Bridge crosses the Hudson River between steep banks some 100 feet high between Washington Heights on north Manhattan and Fort Lee, Bergen County, New Jersey on the mainland side. Fort Washington used to be in the immediate vicinity at the highest point of Washington Heights and Fort Lee on the other side.

It is the only bridge between the island of Manhattan and the mainland west of the Hudson. Only the Holland Tunnel and the Lincoln Tunnel offer other direct road connections to New Jersey. Downstream there is only the Verrazzano-Narrows Bridge between Brooklyn and Staten Island, upriver the Tappan Zee Bridge, about 25 km further north, is the next bridge over the Hudson River.

 

Traffic

The bridge is operated by the Port Authority of New York and New Jersey.

 

Streets

The George Washington Bridge is part of Interstate 95 from Florida to Maine. The I-95 leads as the New Jersey Turnpike in a wide arc from the west to the bridge, crosses on the other side as a 12-lane Trans-Manhattan Expressway in a trough Manhattan and crosses the Harlem River to the Bronx on the Alexander Hamilton Bridge, where it becomes the Cross Bronx Expressway will. The US Highway 1 and the U.S. Route 9 also go over the bridge, which also accommodates local traffic via various access roads.

Traffic flows in eight lanes on the upper level and six lanes on the lower level, with trucks only being allowed to use the upper level. There is a speed limit of 45 mph (72 km/h), but actual speeds are often lower due to heavy traffic. In 2012, 49,110,921 vehicles crossed the bridge bound for New York, for a total of around 100 million vehicles using the bridge each year.

The bridge is a toll towards New York, the journey from New York to New Jersey is free. Under the 2012-2015 toll rate schedule, the toll rate for motorcycles to cross the bridge was $12 cash, $9.25 with EZ Pass during peak commute hours and $7.25 off-peak hours and for cars $13 cash and $10.25 EZ-Pass (peak) and $8.25 EZ-Pass off-peak. There are also discounts for cars that are occupied by at least three people or have good emission values. Truck rates vary between $19 (2-axle, nighttime, with EZ Pass) and $90 (6-axle semi-trailer, cash payment) depending on the time of day or night and number of axles.

Pedestrians and cyclists
Pedestrians and cyclists can cross the bridge free of charge. They share the path on the north side, which is open from 6 a.m. to midnight. This path on the north side, previously closed for many years, was opened in February 2023. As part of repair work on the bridge, it was widened in the area of the pylons and other bottlenecks and had been given new, barrier-free access routes in accordance with the Americans with Disabilities Act. Following the opening of this trail, the trail on the south side was closed for work scheduled to continue through 2027. The Port Authority then intends to direct pedestrian traffic there and cycle traffic on the north side.

Public transport
The Port Authority's George Washington Bridge Bus Station is located in Manhattan at the bridge ramp above Interstate 95 and connects to the upper lanes of the bridge. The bus station primarily serves commuters from the region, but is also served by long-distance bus services. Bus routes from New Jersey Transit and private companies such as Coach USA connect New Jersey and upstate New York west of the Hudson River to the city's mass transit network. MTA Regional Bus Operations bus lines stop on the lower level or outside the bus station on surrounding streets, as do private shared taxis (Jitneys). There are transfers to Line 1 at the 181st Street Subway Station and, through a pedestrian tunnel, to Line A at the 175th Street Subway Station.

Designed by Pier Luigi Nervi in the 1960s and refurbished by the Port Authority in the 2010s, the bus station serves a similar function between New Jersey and New York, but is not to be confused with the larger Port Authority Bus Terminal in Midtown Manhattan served by buses through the Lincoln Tunnel.

 

Description

The George Washington Bridge was built according to the plans and under the direction of Othmar Ammann, officially opened on October 24, 1931 and opened to traffic on October 25.

Its total length is 1451 m (4760 ft), measured from one suspension cable anchorage to the other. Because the bridge connects areas above the high bluffs of the Hudson River, long access ramps were not required and the bridge's roadway could be kept relatively flat. The short spans between the banks and the pylons (192 m for the New York side and 186 m for the New Jersey side) explain that the suspension cables outside the pylons drop unusually steeply to their anchorages. The bridge has a clear height above mean high water of the Hudson River of 64.6 m (212 ft).

The span is 1067 m (3500 ft), which was a new world record at the time of its opening and far exceeded the previous longest span of the Ambassador Bridge (564 m). In 1937 it was replaced by the Golden Gate Bridge with a span of 1280 m.

Its two pylons consist of a plain-looking steel framework construction. At 184 m (604 ft) high, 64 m wide and 17 m thick, they are still unique at these dimensions. Its pillars are connected in the upper third above the roadway by trusses and arches to form portals, the opening of which corresponds to the width of the roadway girder. The pillars are also connected and reinforced by round arches under the roadway girder. The pylon on the New York side is directly on the bank, the pylon on the other side is in the water just before the bank. The pylons were originally supposed to be covered with granite or prestressed concrete slabs, but this was not done because of the sharp increase in construction costs as a result of the global economic crisis.[2] The steel girder construction was nevertheless described in the professional world as elegant and fascinating and the bridge thus became a forerunner of the modern age.

The roadway beam is 36 m (119 ft) wide. The eight-lane roadway laid out in the middle of the upper level is 27.4 m wide. The difference of around 4.3 m on both sides is due to the space required for the suspension cables.

The bridge has four suspension cables, two on each side of the roadway. The carrying ropes are parallel wire ropes produced on the bridge using the air-jet spinning process. Each of the ropes consists of 26,474 individual wires. 434 wires were each combined into 61 strands, which were arranged in a hexagonal profile and formed into round, almost 91 cm thick suspension cables by hydraulic presses and then coated to prevent corrosion. The suspension cables are on the pylons in 162 ton (180 tn.sh.) heavy cable saddles, which were originally arranged openly on the pylon tops, but were covered after two years. The suspension cables are anchored directly into the rock on the New Jersey side, while on the New York side they are anchored in large concrete anchor blocks.

The George Washington Bridge was designated a National Historic Civil Engineering Landmark by the American Society of Civil Engineers in 1981.

On the holidays of Martin Luther King Day, Memorial Day, Independence Day, Labor Day, Washington's Birthday, Columbus Day, Flag Day and Veterans Day, the world's largest freely waving American flag (30 m × 20 m, 215 kg) hoisted.

North of the bridge on the New Jersey side are the Palisades, a forested bluff. Building is prohibited for 15 miles of the strip visible from the Hudson. This was ordered by the owner John D. Rockefeller II, who wanted to protect the view from the museum "The Cloisters" in New York. Rockefeller bought the museum for the Metropolitan Museum of Art in New York in 1925.

 

History

Planning
Since the late 19th century there have been various proposals for bridging the Hudson River, including various designs by Gustav Lindenthal, who wanted to connect midtown Manhattan and New Jersey with a road and rail bridge that would have been significantly larger than the current bridge, but was not carried out due to lack of funds. Othmar Amman worked on the design as an employee of Lindenthal, but soon developed his own ideas.

After his separation from Lindenthal, Ammann proposed a road-only bridge farther north at Fort Lee, where the cost of the land acquisition required was significantly lower and the Hudson was narrower. Initially, to further reduce costs, it was intended to have only one level for six lanes and two wide sidewalks, but designed so that two lanes could later be added and a second level added for suburban motor vehicles and trains. This allowed him to propose a bridge that would cost significantly less and be politically easier to implement than the bridges offered by Lindenthal and other competitors.

Ammann's ideas were accepted; the newly formed Port of New York Authority decided in 1925 to build the bridge and hire Othmar Amman as chief engineer for the design and construction of the bridge. Cass Gilbert was commissioned to provide architectural advice. The planning of the cladding of the pylons with granite slabs goes back to him.

Ammann's final design was revolutionary in many respects: the span of the bridge was almost twice that of the longest bridge built up to that point, and the deck girder had no large trusses for reinforcement. According to the deflection theory, first applied to large suspension bridges by Leon S. Moisseiff on the Manhattan Bridge, the weight of the suspension cables and bridge deck would neutralize much of the lateral wind pressure; a low wind resistance of the flat roadway support is important. Ammann, who had studied this theory intensively and was also advised by Moisseiff, was convinced that the four suspension cables, the great width of the bridge deck and their extraordinarily high weight due to the span were sufficient to withstand even heavy storms. Added to this was the rigidity of the wide and thick pylons and the short outer bridge spans with the suspension cables that fell steeply there.

 

Building

Groundbreaking for the construction of the Hudson River Bridge, as it was originally called, occurred on September 21, 1927. After the pylons and anchors were installed, the wires supplied by John A. Roebling and Sons went from 300 workers to four in 209 workdays Support ropes spun to which the hanging ropes were attached. The suspension of the sections of the bridge deck started at the pylons, so that the last section over the middle of the river closed off the roadway. In 1930 the Port Authority decided to name the bridge the George Washington Memorial Bridge; later this was simplified to the current name.

The bridge was ceremoniously opened on October 24, 1931 by Governors Franklin D. Roosevelt, New York, and Morgan F. Larson, New Jersey - eight months ahead of schedule and well under the budgeted limit.

Even after the collapse of the Tacoma Narrows Bridge, which was a little shorter but with only two lanes and significantly lighter and narrower with only two lanes, in November 1940, Othmar Ammann was firmly convinced that his bridge was stable enough to withstand the dynamic wind forces, which had not been properly understood up to that point . Practice confirmed his view, the bridge showed hardly any vibrations.

 

Extensions

Various expansion options with tram or subway tracks on a second, lower level that were planned when the bridge was planned were not used. The main line of the Independent Subway, the IND Eighth Avenue Line, was planned and built at the same time as the bridge was being built. Underground sidings north of the 168th Street subway station terminate at the trough wall of the Trans-Manhattan Expressway and could have been routed onto the bridge as mainline tracks.

In 1946, as originally planned, the roadway was widened from six to eight lanes. From 1959 to 1962, at the instigation of Robert Moses, the second level, also planned from the beginning, was added below the original one, while traffic continued unchanged on the upper eight lanes. As a result, the bridge was inevitably given a roadway girder that consisted of a high truss construction, so that its rigidity has since been unquestioned.

Between 1977 and 1978 the old upper level concrete roadway was replaced with an orthotropic slab. The prefabricated 3.35 m × 18.30 m (11 ft × 60 ft) elements, which already had the road surface, were installed overnight. In this way, commuter traffic could flow unhindered again the next morning. This was also one of the first uses of an orthotropic slab to reinforce a larger suspension bridge.

 

Bridgegate scandal

Two of the three lanes that direct local traffic from Fort Lee to the toll plaza on the upper deck of the bridge were closed by Port Authority police in September 2013. This unannounced closure, declared as a traffic study, created rush hour congestion during the first work week after the summer vacation and impacted Fort Lee's traffic.

The closure came at the instigation of senior Port Authority officials and on the staff of New Jersey Gov. Chris Christie. In 2016, three suspects in this connection were convicted by a federal court on multiple counts, including conspiracy to commit a crime. Parts of the judgment were overturned by the Supreme Court in 2020 due to unprovable personal gain.
