I-5 - Smokey Point: 172nd St. NE (SR 531) Interchange Modifications & SR 531 Safety Improvements - Complete June 2006
A new bridge at the I-5 interchange with 172nd St. NE improves safety and traffic flow.
The Smokey Point Bridge is located near the City of Arlington in Snohomish County. A two-lane bridge over I-5 was replaced with a six-lane bridge. A bike lane and pedestrian walkway on SR 531 improves safety.
More lanes, a wider bridge, improved lighting and signals, and traffic curb will improve safety by reducing congestion and controlling left turns. A bike lane and walkway on SR 531 improves safety for bicyclists and pedestrians.
The wider bridge and new turn lanes are reducing congestion.
Partnerships & Cooperation
The Tulalip Tribe was one of WSDOT's funding partners in this project. The Tulalip, Stillaguamish, Samish, and Kikiallus Tribes were consulted in November 2002 regarding this project, and a Cultural Resource Survey was prepared. In March 2003, that survey was distributed to these Tribes with a request to review and comment on its contents. After 30 days, the survey was forwarded to the State Historic Preservation Officer (SHPO) who concurred with WSDOT's findings and recommendations--that no tribal resources would be affected by the project--in late April 2003.
This project is funded through the following fund sources:
- Existing Funds - $4,200,000
- Other Agency Funds - $4,948,000
Washington State Transportation Improvement Board ($3.7 million), City of Arlington ($1.2 million), Developer Fees ($48,000)
- Total Funding Available From All Sources - $9,148,000
