Washington State Department of Transportation has published a draft environmental impact statement covering options for the floating bridge that carries the SR 520 over Lake Washington. The 42-year SR 520 Evergreen Point Bridge is very vulnerable to windstorms and earthquakes. The report examines plans and potential effects for a "no build" alternative as well as four-lane and six-lane options. Design options are also explored for the six-lane alternative. The project's estimated cost is up to US$3.1 billion. The comment period will last until 2 October.
