SEATTLE — Beginning next Monday (June 2), a portion of 35th Ave. Northeast, between Northeast 110th Street and Northeast 105th Street, will be closed to through traffic for approximately six months while the city’s longest creek is reshaped to reduce chronic flooding and restore habitat for threatened salmon and other species.
For years, the confluence of the North and South branches of Thornton Creek, just east of 35th Avenue Northeast, has been prone to flooding. High waters have frequently inundated nearby homes, Nathan Hale High School and Meadowbrook Community Center and closed the road to traffic.
To fix the problem, Seattle Public Utilities (SPU) will remove an undersized culvert under 35th Avenue Northeast and realign the existing creek channel through a new two-acre flood plain. The wider channel and flood plain connection will help native fish habitat by spreading out and slowing the peak flows of Thornton Creek.
Additionally, the project will construct a new bridge under 35th Avenue Northeast slightly north of where the creek currently runs.
Meadowbrook Community Center and Pool will remain open during construction and accessible from the south and a detour route is in place for vehicular traffic, bicyclists and pedestrians.
Traffic will be detoured from 35th Avenue Northeast to Lake City Way Northeast via Northeast 110th Street and Northeast 95th Street. Detour signs will be in place prior to the closure and Seattle Department of Transportation will be providing additional pedestrian safety measures, including speed limit signs on NE 110th Street.
Southbound Metro buses (Route 64 and 65) will be detoured to Lake City Way Northeast via Northeast 110th Street and Northeast 95th Street. Northbound Metro buses will be diverted to Sandpoint Way Northeast via Northeast 95th Street and Northeast 110th Street. Find out more information about the road closure as the date approaches.
