A3

The A3 is a major trunk road in the United Kingdom, connecting London with Portsmouth. It passes through South West London, Surrey, Hampshire and into Portsmouth where it links up with other major routes.

The history of the A3 road as we know it today dates back to the 1920s. It was first constructed as the London-Portsmouth Trunk Road, offering a direct route from London to Portsmouth. Over the years, it has been upgraded to reflect the growing importance of motor vehicles, and the recent widening of the A3 into two lanes in each direction has made it one of the busiest roads in the country.

The busiest times on the A3 are usually during rush hour when commuters are travelling to and from work. During the holidays, it can also become very busy as tourists flock to popular destinations located along the route, such as Arundel or Portsmouth.

In terms of traffic flow, the A3 has an average speed of around 63 mph. This is slightly lower than the 70mph national speed limit. However, this is still an impressive speed when taking into account the high levels of traffic that it carries.

The safety statistics for the A3 are generally positive. Since 2013, fatal traffic accidents have decreased by 32%, with less than 5 fatalities reported each year. This is the result of increased enforcement, improved infrastructure and better driver education.
