In 2015, the legislature provided funding for WSDOT to improve the State Route 9 and State Route 204 intersection in Lake Stevens.

The project team is currently refining the design footprint of the SR 9/SR 204 Stakeholder Advisory Group recommended preferred alternative design option. This process involves collecting data identifying environmental impacts, soil conditions, groundwater levels and noise impacts among other things. Based on the data collected design refinements are made to elements of the design such as pedestrian and bicycle facilities.

Why is WSDOT improving the SR 9/SR 204 intersection?
The intersection of State Route 9 and State Route 204 in Lake Stevens experiences congestion that affects Snohomish County commuters, freight mobility and access to local businesses.

The End Result
The initial planning phase resulted in a preferred alternative design option for the SR 9/SR 204 intersection. During this phase, the project team conducted Stakeholder Advisory Group meetings, open houses and community outreach to ensure the chosen design incorporated community input and meets the project needs.
