Content: In 1964, SR 520 was designated as a freeway connecting I-5 to I-405. An extension to Redmond was proposed later in the decade. 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 (HOV lanes) and new interchanges to serve the Overlake area. In 2016, the original Evergreen Point Floating Bridge was replaced by a wider bridge, as part of a multibillion-dollar expansion program that is scheduled to be completed in the 2020s. The program also includes the construction of new bus infrastructure at Montlake and on the Eastside, as well as a bicycle and pedestrian path along most of the highway's length. Contents

SR 520 eastbound approaching SR 202 in Downtown Redmond
SR 520 begins at an interchange with I-5 in northern Seattle near Roanoke Park. The interchange provides access to both directions of I-5 as well as a westbound off-ramp to Harvard Avenue and Roanoke Street. SR 520 travels east across the south end of Portage Bay and its wetlands on the Portage Bay Viaduct, entering the Montlake neighborhood. In Montlake, the highway intersects Montlake Boulevard ( SR 513) and Lake Washington Boulevard just south of the University of Washington campus and Husky Stadium.
