The second weekend is planned for Aug. 19-22 construction on southbound I-5 in Tukwila and southbound State Route 167 in Algona/Pacific. The Washington State Department of Transportation encourages drivers to stay alert, plan ahead and know their alternate routes and transit options.

Final #SouthKingSlowdown work includes SR 167 in Algona/Pacific Aug. 19-22
The second and final weekend of work for the #SouthKingSlowdown is scheduled for Aug. 19-22 in Tukwila and Algona/Pacific.
As lanes are reduced on I-5 in Tukwila to finish replacing expansion joints on the Duwamish River Bridge, crews will close all lanes of southbound SR 167 in Algona/Pacific to complete construction of a 386-foot-long fish passable culvert. SR 167 will be closed from 11 p.m. Friday, Aug. 19, to 5 a.m. Monday, Aug. 22 between Ellingson Road and 8th Street East.
The culvert work on SR 167 and the I-5 lane reductions are 18 miles apart, with several alternate routes for drivers to navigate around them.
This work is a part of the SR 167 Southbound HOT Lane Extension project.
Drivers can help limit backups
The remaining two weekends of highway work will create traffic backups. By planning ahead, drivers can take steps to limit delays:
- Allow extra time to travel through the work zones or on alternate routes.
- Ride transit, carpool or use other forms of transportation.
- Travel early, before 9 a.m., or later, after 9 p.m., or reschedule discretionary trips.
- Check the Seattle Traffic page for updated traffic conditions.
