Latest from WSDOT...
- BELLEVUE – Travelers are advised southbound Interstate 405 in Bellevue and State Route 522 in Bothell will see closures from Nov. 7-10.
- PORT LUDLOW – Travelers on the west side of the Hood Canal Bridge have a safer ride now that the second of two roundabouts on State Route 104 in Jefferson County is complete.
- VANTAGE – Construction activity has paused for the winter. All lanes are now open, and the 9-foot width restrictions have been removed. The speed limit is reduced to 55 miles per hour, and travelers should be cautious of rough transitions between the old and new sections of the bridge deck.
