It’s almost a given that the Washington State Department of Transportation (WSDOT) has weekend projects snarling traffic around the region. This week, however, WSDOT has a few weekday assignments that could affect your routine.
State Route 509 Project — SeaTac
WSDOT continues to move forward on the SR 509 Completion Project. Upon completion, this project will fill critical missing links in the state’s busy highway and freight network, in conjunction with the SR 167 Completion Project.
These lane restrictions and ramp closures have become a regular occurrence for commuters in Kent, Des Moines, Burien, and SeaTac neighborhoods, with work scheduled every week. WSDOT schedules most of these projects in the evenings and overnights, during non-peak hours.
Lane and ramp closures on I-5, SR 516, and SR 509 in Burien, Des Moines, SeaTac, and Kent will continue on Wednesday, Nov. 12, through the morning of Friday, Nov. 14. The lane and ramp closures on I-5 and SR 516 will allow crews to pave and stripe the roads. This work is weather-dependent and may be rescheduled in the event of rain. The SR 509 lane and ramp closures will allow crews to install signage and perform electrical work.
