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, refer to 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; I-5 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.

Note: Commute times are rounded to the nearest minute. GP and HOV commutes include only the freeway section, while transit includes the freeway section and city surface streets. In addition, the transit commute time is influenced by the number of scheduled stop and their times.
