About this drive

On weekdays the 41-mile drive from Los Angeles to ONT (via I-10 East) usually takes as little as 39 minutes and up to 96 minutes, when leaving around 3 pm on Fridays. The fastest times to leave are before 7:30 am or after 9 pm. Midday (11 am to 2 pm) it takes about 52 minutes. On weekends it is slowest around 2:30 pm on Saturdays (55 minutes).

About 36 miles of it is freeway, where times follow typical and live traffic from our sensors, and about 5 miles surface streets (8 to 12 minutes on weekdays), estimated from how jammed the freeways around them are at that time. Drive times are measured from Downtown LA (City Hall) (West 1st Street) to Ontario International Airport (ONT) (Tower Drive) along the route on the map. Starting or ending elsewhere in a big city can add or save several minutes.

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.
