The Evergreen Point Floating Bridge, authoritatively the Governor Albert D. Rosellini Bridge, and normally called the SR 520 Bridge or 520 Bridge, was a gliding span in the U.S. province of Washington that conveyed State Route 520 crosswise over Lake Washington, interfacing Medina with the Montlake/Union Bay region of Seattle.
The scaffold's aggregate length was around 4,750 meters (15,580 ft). Its 2,310 meters (7,580 ft) gliding area was the longest drifting extension on the planet until April 11, 2016, when its substitution surpassed it by 130 feet.
The extension was named for Evergreen Point, the westernmost of the three little Eastside promontories that SR 520 crosses. (The other two are Hunts Point and Yarrow Point.) In 1988, it was renamed for the state's fifteenth representative, Albert D. Rosellini, who had pushed its development.
In spite of the fact that there were plans to supplant the extension quite a long while following its fulfillment, it was not until the point when substantially later that examination uncovered the maturing scaffold to be in poor condition and unfit to withstand the real dangers for which it was initially planned. This finding may have quickened plans to at long last supplant it. Because of these perils and the need to grow the present foundation, development on a substitution started in 2012; the new scaffold opened in April 2016. The first scaffold was shut to movement on April 22, 2016.
The extension was opened for worker activity on August 28, 1963, following three years of development. It was worked as a four-path toll extension to give simple access from Seattle to Eastside people group, for example, Bellevue, Kirkland, and Redmond. The aggregate cost of the scaffold, in 1961 dollars, was $21 million (at any rate $127 million out of 2011 dollars). To compensate for this cost, suburbanites paid a 35-penny toll toward every path until 1979. The toll stalls were then changed over into transport stops.
The extension influenced numerous groups on the Eastside. Redmond's populace saw a sensational increment, bouncing from under 1,500 out of 1960 to 11,000 out of 1970. It was the second drifting scaffold to cross Lake Washington; the first was the Lake Washington Floating Bridge, worked in 1940 as a major aspect of U.S. Highway 10, a later piece of Interstate 90, which in its development was the biggest coasting structure at any point manufactured.
