Measured drive time.Each number is a Google Routes sample of this corridor, not a forecast. Samples are taken every hour, and every 15 minutes from 07:00–08:45 and 16:00–17:45 local. Hours with no bar were not sampled. The latest reading is compared with that same hour on recent weekdays: the median and the 90th percentile. A quiet overnight hour and a jammed morning are not the same kind of typical.
