| HistoricBridges The 958' (292m) long bridge has a main span of 418' (127m). "This vertical lift bridge provides the only direct vehicular access to Roosevelt Island. The bridge does not operate for boats very often, reportedly most openings occur during the United Nations General Assembly when the west channel of the East River is closed to marine traffic for security. The bridge cost $6,498,255.13 to build, and opened May 18, 1955." [I wondered why boats would use the east channel.] |
This shows why the length of the bridge is over twice that of the main span. It has a viaduct over industry on the east side. Consequently, the span has significant clearance when closed.
