From June 14th through September 10th, SDOT will be replacing the old wooden viaduct structure on NE 45th st. This is the segment of NE 45th that connects UW with University Village / Montlake Avenue.
In preparation for the closure, SDOT has released a handy bike, bus & walk map illustrating the temporary re-routes for buses, bicyclists, and pedestrians.
