About Washington State Route 520 in brief
State Route 520 is a state highway and freeway in the Seattle metropolitan area, part of the U.S. state of Washington. It runs 13 miles from Seattle in the west to Redmond in the east. The freeway connects Seattle to the Eastside region of King County via the Evergreen Point Floating Bridge on Lake Washington. The original floating bridge was opened in 1963 as a replacement for the cross-lake ferry system that had operated since the late 19th century. In the 1970s and 1980s, sections of the freeway between Bellevue and Redmond were opened to traffic, replacing the temporary designation of SR 920. Since the 1990s, SR 520 has been expanded with high-occupancy vehicle lanes and new interchanges to serve the Overlake area. Tolls are collected electronically using the state’s Good to Go pass or by mail, and vary based on time of day and the vehicle’s number of axles. As of 2017, tolls for Good togo users range from a minimum of USD 1. 25 between midnight and 5: 00 a.m. and a maximum of USD 4. 30 during the morning and evening peak periods. The State of Washington designates the route as part of its National Highway System, classifying it as important to the national economy, defense, and mobility. The highway is maintained by the Washington State Department of Transportation, which conducts an annual survey on the highway’s volume of traffic in terms of annual traffic. In 2016, it was calculated that 80,000 vehicles traveled on SR520 near its interchange with SR 202 in Redmond, with 47,000 cars used on SR202 at its interchange in Redmond.
The road continues north as Avondale Lake Road towards Cottage Lake towards Downtown Cottage, paralleling a shared-use trail for bicycles and pedestrians for the entire entire route. It was designated as a freeway connecting I-5 to I-405 in 1964, and an extension to Redmond was proposed later in the decade. It is the longest floating bridge in the world; at 7,710 feet, it is the length of the Ever green Point floating bridge, which was built in the 1960s. It has been replaced by a wider bridge that is scheduled to be completed in the 2020s, and will be part of a multibillion-dollar expansion program that will also include a bicycle and pedestrian path along most of the highway’s length. It connects the University of Washington campus and Husky Stadium with the Redmond area of Microsoft and the Nintendo of America branch office. It intersects several state highways, including Interstate 5 in Seattle, I- 405 in Bellevue, and SR 202 in Redmond and terminates in downtown Redmond. The freeway reaches the eastern end of Lake Washington at Ever green point in northern Medina, where it travels under a landscaped park lid and next to a median-side bus station. It continues east on a pair of causeways through the marshlands of Union Bay and Foster Island, at the north end of the Washington Park Arboretum.
