Commute times for the I-5 corridor in the south Puget Sound region
Commute times
This page displays average (mean) and reliable (95th percentile) morning and evening peak commute times for weekday trips on I-5 between Olympia and Federal Way, Olympia and Tacoma, and Tacoma and Federal Way.
The average peak commute times indicate how long it took, on average, to make these trips 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-5 corridor in the south Puget Sound region is served by transit buses. Commute times for GP lanes and transit lanes are shown for each commute trip.

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. In some locations, the travel times in 2022 were close to the pre-pandemic levels.
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, nearly all average and reliable commute times in the general-purpose lanes on the I-5 corridor in the south Puget Sound region either increased or held steady.
