SR 167 HOT Lanes - Removing the Double White Lines

Wondering if you need to upgrade to the new Flex Pass?

SR 167 drivers will only need to upgrade to a Flex Pass if they want to travel free as a carpool on the I-405 Express Toll Lanes between Bellevue and Lynnwood. To use the I-405 express toll lanes as a carpool, you must have an active Good To Go! account and use a Flex Pass in HOV mode.

If you are an existing Good To Go! customer with a switchable pass, you can get a free upgrade to a Flex Pass. Switchable passes will continue to work on SR 167 for now, but we encourage you to upgrade to a Flex Pass since it may be required on the SR 167 HOT lanes in the future. If you have a switchable pass, please contact us to get a free Flex Pass as a replacement.

Better access has arrived for the SR 167 HOT lanes
We've removed the double white line and replaced it with a single white line. Drivers will see just one stripe and can enter and exit the HOT lanes nearly anywhere along the corridor. The HOT lanes are still open to solo drivers with a Good To Go! pass and free to carpools, transit, vanpools and motorcycles.

The end result - Goodbye double white lines!
Here is an animation of how it looks before after construction.

Why did WSDOT change access to the HOT lanes?

Drivers have told us that they want easier access in and out of the HOT lanes. In a 2012 customer survey, 40 percent responded that they did not like restrictive entry and exit points. Transit agencies have also told us it’s tough for them to use the HOT lanes because buses frequently need to enter and exit the highway to make stops.

What’s changed? The HOT lanes are striped with a single white line.
Vehicles are able to change lanes at almost any location instead of at
designated access points.

HOT lanes are still open to solo drivers who choose to pay a toll:
Solo drivers will still need a Good To Go! pass and the lanes are still free to carpools, transit, vanpools and motorcycles.

Double white lines, which are illegal to cross, will remain for about 1 to 2 miles at the ends of the project to eliminate weaving and ensure drivers get the advantage of the reliable trip they paid for.

We’ve collaborated with the Washington State Transportation Center (TRAC) at the University of Washington to create an evaluation plan. The plan will identify how WSDOT will assess the effects of the project on safety, revenue, reliability and speed, customer attitudes, transit operations and lane system performance.

WSDOT applied for and received a $520,000 federal grant to fund the construction and evaluation work.


Feb.-April 2014: Initial work on "before and after" analysis
April 28, 2014: Advertise project
Spring 2014: Open bids
Summer 2014:

  • Remove striping and signage
  • Drivers can enter and exit HOT lanes throughout the corridor
  • Finish collecting and summarize "before" data, prepare for "after" data collection

Late 2014-mid-2015: Collect "after" data, perform major before/after analyses
Fall 2015: Deliver final evaluation report
