Interstate 405 drivers and bus riders count on the express toll lanes for a faster trip when they really need it, but during the peak of the afternoon commute even the fast lanes have their slow spots. Work this week will help address a spot where cars slow down to exit the northbound express toll lane south of State Route 527 by adding a new lane in Bothell to give drivers space to pull out of the express toll lanes before merging into the regular lanes.
Every weekday, about 51,000 drivers choose to get in the express toll lanes. During the peak of the afternoon commute, there are more cars in each express toll lane than in any other lane on I-405, moving an average of 26 miles per hour faster than the regular lanes. But that big demand for the express toll lanes creates a new set of challenges, especially in the areas north of SR 522 where there is only one express toll lane in each direction.
One particularly crowded spot is the northbound area between Northeast 195th Street and SR 527, where nearly 5,000 cars merge into or out of the express toll lanes daily. During the afternoon commute, when many cars in this area are trying to get over to SR 527, cars decrease their speeds in the express toll lane to find a gap in the regular lanes as they merge over. Since there’s only one express toll lane in this area, there’s nowhere for cars to pass slower-moving vehicles, which can create backups behind them.
Addressing the issue
The new lane will help address this issue by giving drivers a place to pull out of the express toll lane before slowing down to merge into the regular lanes. The new lane will stretch for almost one-half of a mile between Northeast 195th Street and SR 527, about as long as eight football fields, to give drivers more space to move over to where they need to be.

This new lane is not to be confused with the new peak-use shoulder lane which opened a couple weeks ago. That improvement gives drivers a new regular lane to use between SR 527 and I-5. The new lane for merging in and out of the express toll lanes is another of more than a dozen improvements to the express toll lanes we’ve made over the past year-and-a-half based on driver feedback. Other improvements have included giving drivers more room to merge and opening the lanes to everyone for free on nights and weekends.
Plan ahead for construction
This week, contractor crews will restripe all the lanes in this area between Northeast 195th Street and SR 527. During this work, I-405 will be reduced to one lane nightly between 9 p.m. and 5 a.m. Please note that this work requires favorable weather conditions to complete the lane striping and wet weather could postpone the work. For the most up-to-date information regarding these closures, please visit the I-405 Construction Update page.
We expect that it may take drivers a little while to get used to the new access point. So be alert when you’re driving through the area, and get ready for the road to look a little different.
