We built new on- and off-ramps on southbound I-5 in Lynnwood. The new on-ramp from SR 525 and I-405 is elevated over a new off-ramp to 196th Street SW. From above, the ramp configuration resembles a braid.
The new ramps separate traffic merging from I-405 and SR 525 to southbound I-5 from traffic exiting southbound I-5 to 196th Street SW. These improvements improve safety by eliminating lane-weaving, which reduces the risk of rear-end and sideswipe collisions.
The new ramps reduce congestion and allow drivers to get on and off the freeway faster and easier.

We upgraded stormwater storage and treatment facilities to ensure water quality for fish and other wildlife.
Partnerships & Cooperation
We started designing the project in September 2006 and advertised it for competitive bidding in April 2010. In June 2010 we awarded the contract to Northwest Construction, Inc., who submitted the most competitive bid. Construction began in August 2010 and crews opened the new ramps to traffic in September 2011. They completed final paving and striping in summer 2012.
