information from Seattle Department of Transportation
Since the West Seattle High-Rise Bridge closure, SDOT has implemented 170+ improvements to keep people moving across the Duwamish and throughout West Seattle, including adding new speed radar signs to Sylvan Way SW last weekend.
This weekend’s work includes:
Intersection improvement at 16th Ave SW and SW Holden St
At the 16th Ave SW and SW Holden St intersection, SDOT will be putting in new turn pockets so drivers can make protected left turns to go east and west on SW Holden St.
To limit the cut-through traffic on 20th Ave SW, SDOT will be installing new signs to better identify the arterial streets near the intersection. In addition, we’ll also be making signal timing adjustments to help people get through the intersection better.
