The A308(M) is a motorway in Berkshire, England. It is Script error: No such module "convert". long. It forms part of the Maidenhead bypass and runs from the M4 at junction 8/9 to the A308 south of Maidenhead town centre. The A308(M) is generally considered to be Britain's second shortest motorway, after the A635(M) on the Mancunian Way.[1]

History

In 1961[2] the A4(M) was opened and ran from the existing junction 7, through a junction with the A308 and ending at a junction with the A4. In 1963, the Slough bypass was opened[2] to junction 7 and the A4(M) was renumbered M4, junction 8 being with the A308 and junction 9 with the A4.

The proposed route of the M4 was then changed to go south of Reading, instead of north of it. When the M4 was extended in 1971,[2] a new junction was provided to connect with what would become a spur. This new interchange was built too close to the original junction 8, so this had to be closed. A new junction (numbered 8/9 so as not to confuse motorists) was built. The original M4 north of this was renumbered as the A423(M) and in the 1990s this was again reclassified as the A404(M). A new spur, the A308(M), was built to maintain access to the A308 and connected with the A404(M) and the M4 at the same grade separated roundabout.
