TheHigh Bridge (originally theAqueduct Bridge) is a steelarch bridge connecting theNew York City boroughs ofthe Bronx andManhattan. Rising 140 ft (43 m) over theHarlem River, it is the city's oldest bridge, having opened as part of theCroton Aqueduct in 1848. The eastern end is located in theHighbridge section of the Bronx near the western end of West 170th Street, and the western end is located inHighbridge Park in Manhattan, roughly parallel to the end of West 174th Street.[4]
High Bridge was originally completed in 1848 with 16 individual stone arches. In 1928, the five that spanned the Harlem River were replaced by a single 450-foot (140 m) steel arch. The bridge was closed to all traffic from around 1970 until its restoration, which began in 2009. The bridge was reopened to pedestrians and bicycles on June 9, 2015.
The bridge is operated and maintained by theNew York City Department of Parks and Recreation.
The High Bridge was part of the first reliable and plentiful water supply system in New York City. As the City was devastated bycholera in 1832 andthe Great Fire in 1835, the inadequacy of the water system of wells-and-cisterns became apparent. Numerous corrective measures were examined.[5] In the final analysis, only theCroton River in northern Westchester County was found to carry water sufficient in quantity and quality to serve the City. The delivery system was begun in 1837, and was completed in 1848.[5]
The OldCroton Aqueduct was the first of its kind ever constructed in the United States. The innovative system used a classic gravity feed, dropping 13 inches (330 mm) per mile, or about 1/4" per 100' (~0.02%)[6] and running 41 miles (66 km) into New York City through an enclosed masonry structure crossing ridges, valleys, and rivers. University Avenue was later built over the southernmost mainland portion of the aqueduct, leading to the bridge. Though the carrying capacity was enlarged in 1861–1862 with a larger tube, the bridge became obsolete in 1910 with the opening of theNew Croton Aqueduct.[5] In the 1920s, the bridge's masonry arches were declared a hazard to ship navigation by theUnited States Army Corps of Engineers, and the City considered demolishing the entire structure. Local organizations called to preserve the historic bridge, and, in 1927, five of the original arches across the river were replaced by a single steel span, while the remaining arches were retained.[1]
Originally designed as a stonearch bridge, the High Bridge had the appearance of aRoman aqueduct. Construction on the bridge was started in 1837, and was completed in 1848 as part of theCroton Aqueduct, which carried water from theCroton River to supply the then burgeoning city of New York some 10 miles (16 km) to the south. The bridge has a height of 140 ft (43 m) above the 620-foot-wide (190 m) Harlem River, with a total length of 1,450 ft (440 m).[1] The design of the bridge was originally awarded to MajorDavid Bates Douglass, who was fired from the project.[7] The design then fell to the aqueduct's engineering team, led byJohn B. Jervis.James Renwick Jr., who later went on to design the landmarkSaint Patrick's Cathedral onFifth Avenue inMidtown Manhattan, participated in the design.
The Croton Aqueduct had to cross the Harlem River at some point, and the method was a major design decision. A tunnel under the river was considered, but tunneling technology was in its infancy at the time, and the uncertainty of pursuing this option led to its rejection. This left a bridge, with the Water Commission, engineers and the public split between a low bridge and a high bridge. A low bridge would have been simpler, faster, and cheaper to construct. When concerns were raised to theNew York Legislature that a low bridge would obstruct passage along the Harlem River to theHudson River, a high bridge was ultimately chosen.
The contractors for the project wereGeorge Law, Samuel Roberts and Arnold Mason.[8] Mason had prior engineering experience working on theErie Canal and theMorris Canal.[9]
In 1864, a pedestrian walkway was built across the High Bridge. TheNew York City Department of Parks and Recreation which is responsible for its maintenance, described the walkway as the bridge's contemporaryHigh Line.[10]
As part of a U.S. federal government initiative to improve navigation along the Harlem River, in 1923, aNew York City Board of Estimate committee recommended demolishing the High Bridge. The bridge's stones would have been reused for a bridge carryingRiverside Drive aboveDyckman Street inInwood, Manhattan.[11] In 1928, the five masonry arches that spanned the river were demolished and replaced with a single steel arch of about 450 feet (140 m).[1] Of the masonry arches of the original 1848 bridge, only one survives on the Manhattan side, while nine survive on the Bronx side.
Use of the structure to deliver water to Manhattan ceased on December 15, 1949.
By 1954,The New York Times reported that the commissioner of the Department of Water Supply, Gas and Electricity said that "the bridge entailed serious problems of maintenance and vandalism".[12]Robert Moses agreed to take responsibility for the bridge, which was transferred to the Parks Department in 1955.[13] There were incidents, in 1957 and 1958, of pedestrians throwing sticks, stones, and bricks from the bridge, seriously injuring passengers onCircle Line tour boats which passed under the bridge.[14] The bridge was closed by 1970, when high crime and fiscal crisis led to the contraction of many city services and public spaces.[5] However, a reporter forThe New York Times wrote that when he had tried to walk across the bridge in 1968, it was closed.[15] TheNew York City Landmarks Preservation Commission (LPC) designated the High Bridge as a city landmark on November 15, 1970.[16][17]
In November 2006, the Department of Parks and Recreation announced that the bridge would reopen to pedestrians in 2009.[18] This date was repeatedly put off. A $20 million renovation project would include strengthening the arch, improving staircases, cameras on both ends of the bridge, and boat beacon lights among other features.[19]
In 2009, preliminary planning, funded byPlaNYC, began for restoring the High Bridge.[18] The High Bridge Coalition raised funds and public awareness to restore High Bridge to pedestrian and bicycle traffic, joining the Highbridge Parks in both Manhattan and the Bronx that together cover more than 120 acres (0.49 km2) of parkland, and providing a link inNew York's greenway system.[20] In early 2010, a contract was signed with Lichtenstein Consulting Engineers and Chu & Gassman Consulting Engineers (MEP sub-consultant) to provide designs for the restored bridge.[21]
On January 11, 2013, the mayor's office announced the bridge would reopen for pedestrian traffic by 2014,[22] but in August 2014, the open was postponed to spring of 2015.[23] In May 2015, the Parks Department announced a July opening[24] and a July 25 festival.[25] The ribbon was cut for the restored bridge at about 11:30 a.m. on June 9, 2015, with the bridge open to the general public at noon.[22][26][27] The High Bridge was illuminated at night following its restoration.[28]
TheHigh Bridge Water Tower, inHighbridge Park between West 173rd and 174th streets, on top of the ridge on the Manhattan side of High Bridge, was built in 1866–1872 to help meet the ever-increasing demands on the city's water system. The 200-foot (61 m) octagonal tower, which was authorized by the State Legislature in 1863, was designed byJohn B. Jervis, the engineer who supervised the building of the High Bridge Aqueduct. Water was pumped up 100 feet (30 m) to a7-acre (2.8 ha) reservoir next to the tower – now the site of aplay center and public pool built in 1934–1936 – which then provided water to be lifted to the tower's 47,000 US gallons (180 m3) tank. This "high service" improved the water system's gravity pressure, necessary because of the increased use offlush toilets.[29][30][31]
The High Bridge system reached its full capacity by 1875.[31] With the opening of the New Croton Aqueduct in 1890, the High Bridge system became less relied upon; duringWorld War I, it was completely shut down when sabotage was feared.[31] In 1949, the tower was removed from service,[29][31] and acarillon, donated by the Altman Foundation, was installed in 1958.[31]
The tower's cupola was damaged by an arson fire in 1984. It was reconstructed, and the tower's load-bearing exterior stonework – which Jervis designed in a mixture ofRomanesque Revival andneo-Grec styles – was cleaned and restored in 1989–1990 by the William A. Hall Partnership.[30][31]Christopher Gray has said of the tower's design that "Its rock-faced granite gives the tower a chunky, fortified appearance, as if it were a lookout for a much larger castle complex that was never built.... The granite is competently handled, but the details are not very inspired or elegant. The tower is more picturesque than beautiful."[31]
The interior of the tower, which was never open to the public, features a wide well-detailediron spiral staircase with six large landings and paired windows.[31]
The High Bridge Water Tower was designated aNew York City landmark by theLandmarks Preservation Commission in 1967.[29] The High Bridge Water Tower underwent a 10-year, $5 million renovation during the 2010s and reopened to the public in November 2021.[32][33] After the water tower reopened, NYC Parks began hosting free tours of the structure.[34]
