Route

The start of the A308(M)

Just over half a mile long, the route of the A308(M) can almost be described in a single sentence. The motorway starts at a roundabout with the main A308 and A330, and ends only yards down the road at M4 junction 8/9. It is perhaps the only motorway in the country which has no flyovers or underpasses, as no roads cross it during its short trip to the M4, although the original line of the M4, now returned to nature, can be seen crossing it just to the north of the M4 roundabout.

History

The reason this road exists is as a replacement for the closed M4 junction 8. This junction, a LILO, was closed when the M4 was extended from a point just west (the site of the present day Junction 8/9). As a result of the loss of junction 8, which was with the A308, a new road was built, so the A308 didn't lose its access to the M4. As the other road at Junction 8/9 was a motorway, the A404(M), the new road also had to be a motorway, and so the A308(M) was born.

Opening Dates

The A308(M) opened in its entirety in 1971.
