Junctions related to the A33

Popham Interchange is junction 8 of the M3, where it splits into the M3 to Southampton and the A303 towards Exeter. It also covers the junction of the A303 and A30 at the end of the spur, and the A33 which meets the A30 here and used to terminate the M3.

History

Popham Interchange in 1932


Popham Interchange in 1959
Popham Interchange in 1974

This junction has always consisted of a split - at the time of classification, the A33 took the mainline with an unclassified road heading to Stockbridge which was quickly upgraded to the B3379, but it is better known as the fork between the A33 to Southampton and the A30 to Exeter, with the A30 taking priority in a multiplex to the north. This part of the junction has been in place since 1 April 1933 and hasn't changed today.

When the M3 opened in 1971, it split into two roads next to the existing junction, with the first road terminating on the A33 just south of here and the second on the A30 just west of here. The two terminal junctions were identical forks.

In 1985 the M3 was extended to the south, alongside the A33, with the terminal junction being closed. The A30 west of here has since been upgraded to A303, but that fork junction remains intact.
