Sonoma Raceway Related Traffic

Please be sure to check the Sonoma Raceway schedule as Highway 37 can get extremely blocked with traffic. If there is a race during the weekend of your scheduled arrival date, it is normally the busiest on Saturdays and Sundays in both north and south directions.

Late Weekday Afternoon Traffic

Highway 37 on weekday afternoons/evenings (4-6pm) also generally has heavy traffic. We recommend taking Highway 116 as an alternate route from Hwy 101. See below for an alternate route taking Hwy 116 from Hwy 101. Click here to check the Sonoma Raceway schedule.
