Due to regional economic development and the demand for affordable housing, the population of Snohomish County increased by nearly 80 percent between 1980 and 2000.
This population growth has caused an influx of traffic on SR 9 throughout Snohomish County. The once rural road is now a critical corridor for both commercial vehicles and commuters. Current traffic volumes have exceeded the capacity of the two-lane roadway, making the once free-flowing, rural SR 9 a congested highway during peak travel times.
Between 2000 and 2017 WSDOT will invest $300 million to transform SR 9 from a rural road into a wider, safer highway.
Why is WSDOT
studying the options for widening SR 9 between Marsh Road and 2nd Street, including a new southbound bridge?
Approximately 27,000 vehicles use that section of highway everyday. That number is expected to increase with future development in the area. The current two-lane highway is insufficient to meet the growing demand.
WSDOT will explore options for widening SR 9 between Marsh Road and 2nd Street, including a new southbound bridge over the Snohomish River and connecting it to other widening projects on SR 9. These projects are subject to funding by the Legislature.
The End Result
Through this environmental documentation study, WSDOT will:
- Choose a preferred alternative for highway widening and a new southbound bridge.
- Formulate a cost estimate that will allow WSDOT to pursue funding.
This study is the first step in widening SR 9 from two lanes to four between Marsh Road and 2nd Street. It will also help identify the type, size and location of a new southbound bridge.
What is the project timeline?
The study began in early 2010 and is expected to be completed in June 2013.
Pre-existing funds: $1.5 million
Total funding from all sources: $1.5 million
