A new day, a new way
|The braided ramp system in Bothell is nearing completion.|
What’s going on here? Currently, on an average weekday, the 30,000 drivers who take northbound I-405 to State Route 522 must weave between 12,000 drivers entering northbound I-405 from Northeast160th Street. Throughout the day, those 42,000 cars vying for room cause unnecessary traffic and delays. The new braided ramp system will separate drivers heading to SR 522 from those heading to northbound I-405, eliminating the need to weave and ensuring a safer, more efficient trip.
Weekend closures ahead
|With the new braided ramp system, drivers|
entering State Route 522 from northbound
I-405 can bypass drivers entering
I-405 from NE 160th Street.
After Monday, drivers may also want to allow extra time to adjust to the new on- and off-ramp arrangement. Folks on northbound I-405 will have to exit a little earlier to take SR 522, because the new ramp will begin just under the NE 160th Street overpass.
If you’re entering the system from Northeast 160th Street, you will have to choose ahead of time whether you want to continue to northbound I-405 or drive directly to SR 522.
What’s a braided ramp?While the word braid is associated with knots, this ramp configuration is given its name because of its resemblance to braided hair from an aerial view. Braided ramps actually eliminate lines on entrance ramps by decreasing traffic weaving. Braided ramp systems also improve safety for drivers. Studies on a San Antonio highway showed that separating drivers reduced crash frequencies by 71 percent.
We now interrupt this blog post to bring you information on the I-405 express toll lanes…coming this September
We need to set aside the braided ramps for a moment to tell you about another key component of the Bellevue to Lynwood Widening and Express Toll Lane project. You guessed it, express toll lanes. They are coming in September. Are you Good To Go? Do you have a Flex Pass or even know what a Flex Pass is? We’ll break it all down for you at GoodToGo405.org and tell you how to prepare.
And now back to your braided ramps messaging…
Don’t’ forget, it’s “a new day, a new way” Monday morning on August 31!
