SEATTLE — Are you coming back from a road trip after visiting family and friends this Memorial Day weekend? The Washington State Department of Transportation (WSDOT) released travel charts for three state highways expected to see higher than usual traffic over the holiday weekend to help drivers plan ahead.
WSDOT said drivers could experience higher than usual traffic on highways between May 26-31, especially on I-90 “where lengthy delays are expected.” I-90 runs across Snoqualmie Pass and stretches through almost the entire state from Seattle to Spokane.
WSDOT traffic analysts created the charts by looking at how many cars were on roads during previous Memorial Day weekends. WSDOT said drivers can expect some congestion on the roads when the charts turn from green to yellow. When the chart is red, the WSDOT said the roadway is predicted to be at capacity.
“Once a roadway reaches capacity, any small incident can cause significant backups,” WSDOT said.
The black line on the graph shows what traffic is like on a typical weekend.
I-5 between Lacey and Tacoma
Anyone driving on I-5 between Lacey and Tacoma should expect moderate to heavy traffic with some congestion at times each day over the Memorial Day weekend. However, the WSDOT charts show traffic is predicted to be about the same as a typical weekend.
Northbound drivers should expect the heaviest traffic on Thursday between 5 a.m. and 2 p.m., Friday between 6 a.m. and 5 p.m., Saturday between 9 a.m. and 4 p.m., Sunday at 10 a.m. and between 1-8 p.m., Monday between 10 a.m. and 9 p.m. and on Tuesday from 5 a.m. until 5 p.m.
Southbound drivers should expect about the same. According to the WSDOT, drivers should expect the heaviest congestion between 7 a.m. and 8 p.m. on Thursday and Friday, on Saturday between 8 a.m. and 5 p.m., Sunday between 10 a.m. and 3 p.m. and on Tuesday between 7 a.m. and 6 p.m.
Southbound traffic on Memorial Day is predicted to be less congested than a typical day, with the highest travel times between 11 a.m. and 2 p.m.

I-90 between North Bend and Cle Elum
Eastbound traffic on I-90 over Snoqualmie Pass is expected to be higher than normal on Thursday but not reach capacity.
Traffic on Friday, however, is predicted to be above normal for most of the day. The WSDOT said eastbound traffic is expected to be “moderate to heavy” between 7-10 a.m. and 8-9 p.m. The roadway is expected to reach capacity from 10 a.m. until 7 p.m. Friday.
Traffic will also be higher than normal on Saturday, with the heaviest congestion expected between 8 a.m. and noon. Eastbound traffic is predicted to be at or below a typical weekend from Sunday to Tuesday.
Westbound traffic is expected to be at or below a typical weekend between Thursday and Sunday. However, westbound drivers should “expect congestion” between 2-5 p.m. on Sunday, but it’s predicted to be less than the average weekend.
On Memorial Day, drivers should steer clear of westbound I-90 from 9 a.m. until 8 p.m. to avoid the worst congestion.
