Last year during a routine inspection of the 97-year-old southbound State Route 529 Steamboat Slough Bridge just south of Marysville, our crews found about a dozen worn gusset plates, which connect steel beams. We'll replace these worn plates in a few weekend-long closures.- SEATTLE – Bicyclists and pedestrians traveling across Lake Washington should plan for an extended State Route 520 Trail closure. The around-the-clock closure starts at 10 p.m. Friday, Jan. 19, and wraps up at 1 p.m. Friday, Feb. 2. Crews will close the portion of the trail between the Montlake neighborhood in Seattle and the Evergreen Point Lid in Medina.
