from the Washington Department of Transportation
Fast-growing numbers of people depend on the State Route 520 link across Lake Washington, but the 42 year-old Evergreen Point Bridge is often crowded with cars and always very vulnerable to windstorms and earthquakes. The Washington Department of Transportation is planning to replace the span, with either a four-lane or six-lane bridge.
Both alternatives will create a seismically sound and safe new Portage Bay Bridge and Evergreen Point Floating Bridge with full shoulders and a bike and pedestrian path . Both alternatives include pontoons large enough to support future high-capacity transit.
The Department of Transportation held “open house” style public hearings in Seattle and Bellevue on Sept. 18 and 21 for the project. People have until Oct. 31 to learn about the project and make comments.
Receiving the public’s feedback on the draft EIS is an important step in the process to help regional decision-makers and the Department of Transportation identify a preferred alternative for replacing the bridge and improving the SR 520 corridor. The draft EIS evaluates both the four-lane alternative and six-lane alternative, as well as six-lane design options.
The SR 520 Bridge is vulnerable not only to earthquakes, but also to windstorms and high waves. The bridge was closed twice last winter when storm winds exceeded 50 mph. With every year that passes, the SR 520 Evergreen Point Bridge gets closer to the end of its useful life and must be replaced.
