About A308 Motorway
The A308 is a motorway in Berkshire, England. It is 0. 6 miles 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. HistoryIn 1961 the A4 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 to junction 7 and the A4 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, 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 was built. The original M4 north of this was renumbered as the A423 and in the 1990s this was again reclassified as the A404. A new spur, the A308, was built to maintain access to the A308 and connected with the A404 and the M4 at the same grade separated roundabout.
