The '''Manhattan Bridge''' is a [[suspension bridge]] that crosses the [[East River]] in [[New York City]], connecting [[Lower Manhattan]] at [[Canal Street (Manhattan)|Canal Street]] with [[Downtown Brooklyn]] at the [[Flatbush Avenue Extension]].  Designed by [[Leon Moisseiff]], the bridge has a total length of {{convert|6855|ft|m|0|abbr=on}}. The bridge is one of four vehicular bridges directly connecting Manhattan Island and [[Long Island]]; the nearby [[Brooklyn Bridge]] is just slightly farther west, while the [[Queensboro Bridge|Queensboro]] and [[Williamsburg Bridge|Williamsburg]] bridges are to the north.<ref>{{cite web | last=Sharif | first=Mo | title=Protecting New York City's Bridge Assets | website=Federal Highway Administration | date=December 19, 1903 | url=https://highways.dot.gov/public-roads/mayjune-2005/protecting-new-york-citys-bridge-assets | archive-url=https://web.archive.org/web/20210429221316/https://highways.dot.gov/public-roads/mayjune-2005/protecting-new-york-citys-bridge-assets | url-status=dead | archive-date=April 29, 2021 | access-date=January 8, 2025}}</ref>

The bridge was proposed in 1898 and was originally called "Bridge No. 3" before being renamed the Manhattan Bridge in 1902. Foundations for the bridge's suspension towers were completed in 1904, followed by the anchorages in 1907 and the towers in 1908. The Manhattan Bridge opened to traffic on December 31, 1909, and began carrying streetcars in 1912 and [[New York City Subway]] trains in 1915. The eastern upper-deck roadway was installed in 1922. After streetcars stopped running in 1929, the western upper roadway was finished two years later. The uneven weight of subway trains crossing the Manhattan Bridge caused it to tilt to one side, necessitating an extensive reconstruction between 1982 and 2004.

The Manhattan Bridge was the first suspension bridge to use a [[Warren truss]] in its design. It has a main span of {{convert|1480|ft|m|0|abbr=on}} between two {{Convert|350|ft|adj=on}} suspension towers. The deck carries seven vehicular lanes, four on an upper level and three on a lower level, as well as four subway tracks, two each flanking the lower-level roadway. The span is carried by four main cables, which travel between masonry anchorages at either side of the bridge, and 1,400 vertical suspender cables. [[Carrère and Hastings]] designed ornamental plazas at both ends of the bridge, including an arch and colonnade in Manhattan that is a [[New York City designated landmark]]. The bridge's use of light trusses influenced the design of other long suspension bridges in the early 20th century.

The bridge repairs were repeatedly delayed as the renovation process uncovered more serious structural problems underlying the bridge.

The arch and colonnade had also become deteriorated, having become covered with graffiti and dirt.
