About this drive

On weekdays the 14-mile drive from Cambridge to Quincy (via I-90 East and I-93 South) usually takes as little as 19 minutes and up to 56 minutes, when leaving around 4:30 pm on Thursdays. The fastest times to leave are before 6 am. Midday (11 am to 2 pm) it takes about 31 minutes. On weekends it is slowest around 3 pm on Saturdays (39 minutes).

About 10 miles of it is freeway, where times follow typical and live traffic from our sensors, and about 4 miles surface streets (9 to 28 minutes on weekdays), estimated from how jammed the freeways around them are at that time. Drive times are measured from central Cambridge (Ellery Street) to central Quincy (Faxon Avenue) 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.
