The Washington State Department of Transportation (WSDOT) will install sign bridges and toll structures on State Route 167 (SR 167). This work needs a full closure of the highway between 277th Street and West Willis Street/State Route 516 (SR 516) in both directions of SR 167. This 1.5-mile section will close Thursday at 10 p.m. through Friday at 4 a.m., with a detour in place.
Once complete, this will be part of the long-term plan to connect a 50-mile express toll-lane system between Lynnwood and Puyallup. This work is part of the SR 167 Corridor Improvements Project.
The following on- and off-ramps will also be closed:
- West Willis Street/SR 516 on-ramp to southbound SR 167.
- South 277th Street on-ramp to northbound SR 167.
- Northbound SR 167 off-ramp to West Willis Street/SR 516.
- Southbound SR 167 off-ramp to South 277th Street.
WSDOT crews will remove signs from Interstate 405 (I-405) southbound through Canyon Park, part of the I-405/Brickyard to SR 527 Improvement Project.
Expect intermittent full I-405 closures during WSDOT’s Thursday overnight work
The plan is to have as little impact to drivers as possible, with lane closures beginning Thursday at 8 p.m. approaching State Route 527 (SR 527). At midnight, contractors will have intermittent full closures on I-405 to safely remove signs over the freeway, stopping traffic for up to 15 minutes.

This is a short three-hour closure, reopening by midnight on Thursday.
