When did the M3 open and how long is it?
The M3 runs from Sunbury-on-Thames, Surrey, to Eastleigh, Hampshire.
It is approximately 59 miles (95 km) long.
The M3 includes major towns and cities including Aldershot and the surrounding urban area, Basingstoke, Winchester, and Southampton.
It was originally approved as the “London to Basingstoke” motorway.
The M3 was constructed as a dual three-lane motorway except for its two-lane section between junction 8 (A303) and junction 9.
The motorway was opened in phase, starting with the eastern section from 1971 onwards.
This stretched from Sunbury-on-Thames, Surrey to Popham near Basingstoke: starting with the Hampshire section in 1971 and then the Surrey section in 1974.
It has been reported that the cost of this first section was £46m.
The completed M3 eastern section acts were as a continuation of the A316 Country Way, an express three-lane road from Apex Corner, Hanworth, in Greater London to Sunbury-on-Thames.
The southern section of the motorway came later, following an inquiry called “M3 London to Basingstoke Motorway: Popham to Compton extension”.
It was first held in 1971 and then again from 1976 to 1977.
The southern section of the M3 was finally completed in 1995.
It was built in two sections from ‘Popham to Bridget’s Farm’ and then again from ‘Bridget’s Farm to Bar End’.
According to reports from 2008, the busiest section of the motorway carried a daily average of around 130,000 vehicles.
