Route description

Originating at Interstate 5 in Seattle at the north end of Capitol Hill just south of Roanoke Park, it crosses Portage Bay on a viaduct, runs through the Montlake neighborhood, and from there runs on a causeway through the marshlands of the Washington Park Arboretum and across Foster Island. It crosses Lake Washington on the Evergreen Point Floating Bridge (1963)--at 7,578 feet, the longest floating bridge in the world--to Medina. From there, it separates Hunts Point and Yarrow Point to the north from Clyde Hill to the south. Intersecting with Interstate 405 in Bellevue, it then runs through Redmond, bisects the Microsoft campus, crosses the Sammamish River and Bear Creek, and ends at Avondale Road N.E.

• Ghost Ramps: SR 520 features a set of ghost ramps in the marshlands of Washington Park Arboretum. They are often referred to as "ramps to nowhere". However, there are 2 ramps currently used for the Westbound 520 off ramp connection to the Washington Park Arboretum while the other serves as an on ramp only to SR 520 Eastbound. The others are unused. They were originally part of a plan to build the R. H. Thompson Expressway which would have cut through the arboretum and down through Seattle towards the I-90/I-5 interchange. Citizens rallied a freeway revolt against the plan on May 4, 1969. Construction near the Arboretum later continued but citizen protest eventually won out and the plan was dropped in 1971. Photos of the ramps can be seen at this link:

Ongoing improvements

Because of massive residential, commercial, and industrial growth in the Eastside over the past 10 years, several projects have been proposed to improve the entire stretch of State Route 520. One notable project is the replacement of the Evergreen Point Floating Bridge with a new structure.

• Replacement of Evergreen Point Floating Bridge and highway expansion between Interstate 5 and Interstate 405.
• Widening of highway between West Lake Sammamish Parkway and State Route 202, along with new and improved ramps.
• Expansion of interchange with 148th Avenue NE in Bellevue's Overlake neighborhood.
• Eastbound collector-distributor lanes between Interstate 405 and 124th Avenue NE.
