Freeway, about 14 miles: times follow typical and live traffic from our sensors. Surface streets, about 12 miles: 27 to 68 minutes on weekdays, estimated from how jammed the freeways around them are at that time (we don't have street sensors yet).

Simulated from typical freeway speeds at each point of the drive for the time you would reach it, from every 5-minute reading we have recorded. We don't have sensors on surface streets yet, so the time on them is estimated from how congested the freeways around each end of the drive are at that time, in both directions: streets jam when the freeways do.
