October 2009
- We have narrowed down a perferred alternative of the three we reviewed.
- We have coordinated with several local agencies including Snohomish County, the city of Lynnwood and their city center access study.
- This project is funded by the 2005 Gas Tax.
Overview
We will build a braided ramp to separate traffic merging from I-405 and SR 525 to southbound I-5 from traffic exiting southbound I-5 to 196th Street in Lynnwood. These improvements will eliminate lane-weaving, help reduce congestion and rear-end and sideswipe collisions.
Why is WSDOT
making these improvements?
Keeping drivers safe is WSDOT’s top priority. Busy residential and retail traffic exiting at 196th Street SW is causing severe backups onto southbound I-5 as fast traffic mixes with slow moving traffic exiting to the 196th Street interchange. These traffic flow problems lead to rear-end and sideswipe collisions.
The End Result
With the braided ramp configuration, drivers exiting to 196th Street SW from southbound I-5 will be separated from the traffic entering southbound I-5 from SR 525 and I-405. These improvements will eliminate lane-weaving, and help reduce rear-end and sideswipe collisions and congestion.
Project Benefits
• Safety - By providing a braided ramp, we will eliminate lane-weaving on the mainline, and decrease rear-end and sideswipe collisions.
• Congestion relief - Drivers will get onto and off the freeway faster, easier and safer.
• Environment - We will upgrade stormwater storage and treatment facilities to ensure water quality for fish and other wildlife.
What is the project timeline?
Engineers and planners are researching and working with local communities to refine the scope of this project. The estimated timeline for the southbound braided ramps are:
September 2006 - Design started
February 22, 2010 - Advertise for competitive bidding for construction
Spring 2010 - Begin construction
Summer 2012 - Estimated construction complete
