Since mid-June, the Washington State Department of Transportation closed a portion of State Route 506 near Vader to replace the aging and failing Lacamas Creek Bridge in Lewis County. While drilling foundations for the replacement structure, WSDOT's contractors, Farline Bridge Inc., discovered dense soil conditions, which will delay the reopening of the highway.

For drivers who regularly experience congestion on Interstate 405 between Renton and Bellevue, help is on the way.

Gov. Jay Inslee joined state and local officials at the Port of Tacoma to help The Washington Department of Transportation (WSDOT) kick off the construction phase on the Puget Sound Gateway Program. The Gateway Program includes two projects — SR 167 completion in Pierce County and SR 509 completion in King County — new connections to the Ports of Seattle and Tacoma and manufacturing and industrial centers that will enhance the state's national and global economic competitiveness.

The January closure of the Alaskan Way Viaduct in downtown Seattle — also known as State Route 99 — was another step in a long reclamation project that will eventually remove the highway and repurpose the land it occupies. According to the Washington State Department of Transportation, removing the viaduct will be completed in three stages: site preparation, demolition and site restoration.

On May 22, 2019, Gov. Jay Inslee ordered the Washington State Department of Transportation to begin the immediate ramp-up of culvert repairs around the state, an urgent and crucial priority for improving fish passage and salmon recovery. Culverts are pipes that allow streams or water to flow under or across a roadway or railroad.

The start of the new year signals dramatic changes ahead for Seattle drivers and commuters. On Jan. 11, 2019, the Alaskan Way Viaduct permanently closes to start three weeks of work needed to open the new State Route 99 tunnel. When the new SR 99 tunnel opens in early February, getting to and from Seattle via SR 99 will be a very different experience than it is today.

Washington State Department of Transportation (WSDOT) is completing work on a wildlife bridge along I-90 near Snoqualmie Pass. The 35-ft.-tall, 66-ft.-wide bridge is currently the largest in the state and is meant to reduce traffic accidents involving humans and animals.

The Washington Department of Transportation (WSDOT) is saving time and money on a transportation safety project by using tons of Geofoam to build a ramp for direct connections from one freeway to another. On HOV/HOT lanes near Renton, drivers must cross numerous general-purpose lanes to get off one highway and onto another.
