Thursday morning traffic continued to prove our analysis from the day prior, which found commuters adjusted to the Alaskan Way Viaduct Closure as similar congestion patterns appeared over the week.
Traffic behaviors have not changed over the last two days during the Alaska Way Viaduct Closure in Seattle. At this point, people have adjusted to different transportation modes, are telecommuting or changed their working hours. Seattle has likely reached the standard traffic pattern during the closure, but DKS will continue analysis if there are any anomalies.
DKS analyzed the traffic impact on the first Monday morning commute with the Alaska Way Viaduct closure in effect in Seattle. The highway system was truly tested; with heavier traffic all around Seattle as more people commuted on Monday in comparison to the closure’s first day last Friday. DKS’ review only includes the live traffic during peak hours, not the … Read more

Traffic analysis for Memorial Day weekend of five west coast cities to come!
The Alaskan Way Viaduct closure had the Seattle freeway system resembling a ten-day heart surgery. As Bertha tunneled under SR 99, the three other corridors leading into the “heart” of Seattle felt the greatest impact. With I-90, I-5 Southbound and I-5 Northbound running under greater traffic pressure, connected “arteries” SR 520 and West Seattle also experienced more delay. The outcome? … Read more
WSDOT opened the Alaskan Way Viaduct one week early as the tunneling process passed safely underneath. Seattle quickly saw relief as it returned to the average 30 percent of main traffic flow going in and out of the city. This morning’s new SR 520 bottleneck traffic shows the true shift in the congestion point after the Viaduct reopened.
Friday AM analysis: Seattle saw significantly more traffic than usual on I-5, I-90, SR520, and West Seattle Bridge on the second Friday morning commute during the 99 closure. With peak traffic hitting around 7:30 a.m. and 8:45 a.m., the corridor congestion dissipated as soon as 9 a.m. hit and commuters mostly made it to their offices. Twitter Tips- #ITSWA15 – … Read more
