Commute times for the I-90 corridor in the Spokane region
Commute times
This page displays average (mean) and reliable (95th percentile) morning and evening peak commute times for weekday trips on I-90 between Division Street and Argonne Road.
The average peak commute times indicates how long it took, on average, to make that trip during the worst part of the morning (or evening) commute in a given year. The reliable peak commute time shows how much time someone traveling during the worst part of the morning or evening commute would have to allow for their trip in order to arrive at their destination on time on 19 out of 20 days. For details on the methodology used to calculate commute times, see WSDOT's Handbook for Corridor Capacity Evaluation (PDF 5.9MB).
Highway capacity constraints vary based on the presence of managed lanes and multimodal travel options; the I-90 corridor is served by transit buses.

Note: a) Transit travel time data was not collected for 2018 due to a pause in publication while WSDOT conducted an engagement process to inform the redesign of this dashboard. Commute times are rounded to the nearest minute. b) In 2021, we changed our data sources, which causes the decrease of the posted speed.
Multi-year trends
In 2022, travel times in most locations continued to worsen compared to 2021 due to the ongoing recovery of traffic volume in the wake of COVID-19. However, the travel times were slightly better than the pre-pandemic levels. The five new ramp meters have helped reduce the length and duration of congestion.
In 2020, due to the statewide response to COVID-19 there was a significant decrease in commute times compared to previous years.
From 2018 to 2019, Argonne Road to Division Street westbound peak morning commute travel times on I-90 held relatively steady, but evening commute travel times decreased.
Annual highlights
In 2022, the average morning commute times for westbound I-90 were relatively unchanged when compared to 2021. The average travel times for eastbound I-90 in contrast worsened compared to 2021 in the evening peak periods. The eastbound 7.5-mile trip from Division street to Argonne road during the peak evening commute took an average of 11 minutes—four minutes more than it should take at the posted speed limit, but seven minutes less than the reliable travel time of 18 minutes. The average travel time via transit was nine minutes (with a reliable travel time of 13 minutes). The 7.5-mile trip from Argonne road to Division street during the peak morning commute took an average of nine minutes—two minutes more than it would take at the posted speed limit, but four minutes below the reliable travel time of 13 minutes. The average travel time via transit was eight minutes (with a reliable travel time of nine minutes).
In 2021, travel times for eastbound and westbound I-90 are still better than pre-pandemic level. The eastbound 7.5-mile trip from Division street to Argonne road in the GP lanes during the peak evening commute took an average of nine minutes—two minutes more than it should take at the posted speed limit. This evening nine minute average commute is six minutes below the reliable travel time of 15 minutes. The average travel time via transit was eight minutes (with a reliable travel time of 11 minutes). The 7.5-mile trip from Argonne road to Division street in the GP lanes during the peak morning commute took an average of nine minutes—two minutes more than it would take at the posted speed limit. This morning nine minute average is five minutes below the reliable travel time of 14 minutes. The average travel time via transit was nine minutes (with a reliable travel time of 12 minutes).
In 2020, due to the statewide response to COVID-19 there was significant decrease in commute times compared to previous year. The 7.5-mile trip from Division street to Argonne road in the GP lanes during the peak evening commute took an average of eight minutes—it was same minutes it should take at the posted speed limit, and six minutes below the reliable travel time of 12 minutes. The average travel time via transit was eight minutes (with a reliable travel time of 12 minutes). The 7.5-mile trip from Argonne road to Division street in the GP lanes during the peak morning commute took an average of eight minutes—it was same minutes it should take at the posted speed limit, and two minutes below the reliable travel time of 10 minutes. The average travel time via transit was 12 minutes (with a reliable travel time of 14 minutes).
In 2019, the 7.5-mile trip from Division street to Argonne road in the GP lanes during the peak evening commute took an average of 11 minutes—three minutes more than the eight minutes it should take at the posted speed limit, and three minutes below the reliable travel time of 14 minutes. The average travel time via transit was 12 minutes (with a reliable travel time of 14 minutes).
