That is about the same as the A3 runs on an average day. Hours outside 06:00 to 22:00 are shown but greyed: the small hours are the fastest on almost every road in England, which is true and useless for planning. Averaged across 5 sensors on the A3.

Questions about the A3 on a Saturday
What is the best time to drive the A3 on a Saturday?
On a Saturday the quietest hour on the A3 is 19:00, when traffic averages 67 mph. That is a measured average from National Highways roadside sensors on the road itself, recorded between 1 May 2026 and 15 June 2026, rather than an estimate. Only 06:00 to 22:00 is considered, because the small hours are the fastest on almost every road in England and saying so helps nobody plan a journey. Roadworks, collisions and weather are not in the average, so it describes what this Saturday usually looks like rather than what today will look like.
What time is the A3 busiest on a Saturday?
The busiest hour on the A3 on a Saturday is 11:00, averaging 64 mph, about 4% below the speed the road runs at when it is clear. The comparison is against this road's own free-flowing speed, so "slower" means slower than the A3 normally manages rather than slower than some national figure. Measured from roadside sensors between 1 May 2026 and 15 June 2026. It is an archive of the usual pattern, not a live reading, so check conditions before you set off.
