This page displays average (mean) and reliable (95th percentile) morning and evening peak commute times for weekday trips on I-205 between the I-5/I-205 interchange and the I-205 Glenn Jackson Bridge.
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 methodology to calculate commute times, refer to WSDOT's

Note:Travel times at posted speed are different in some years for some commutes due to the change in the trip length caused by changes in data collection device locations. 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.
