The A308(M) is a motorway in Berkshire, England. It is 0.6 miles (1km) long [http://pathetic.org.uk/current/a308m/ Pathetic Motorways - A308(M)] ] and is possibly England's shortest motorway [http://www.cbrd.co.uk/motorway/a308m/ CBRD Motorway Database - A308(M)] ] , although the westbound carriageway of the A64(M) is shorter. It runs from the M4 at junction 8/9 to the A308.

History

In 1961 [http://www.iht.org/motorway/m4loswstat.htm The Motorway Archive - M4 Dates Page] ] the A4(M) [ [http://pathetic.org.uk/former/a4m/ Pathetic Motorways: 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 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 [ [http://pathetic.org.uk/current/a404m/ Pathetic Motorways - A404(M)] ] . 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 (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.
