Awkley Interchange is junction 21 of the M4. It is the eastern of two connections with the M48.

History

The M48 was originally part of the M4, taking the motorway to the Severn Crossing. When the Second Severn Crossing was constructed in 1996, the M4 took a more southerly route, and the former M4 became the M48. This junction marks the eastern end where the old and new routes meet; the roads meet again at Rogiet Interchange.

Since both the M4 and the M48 head for crossings over the Severn, there seemed to be no reason to build a link between the M4 eastbound and M48 westbound (and vice-versa) so this is a simple fork junction. (Although some might argue a connection would be useful for diverted traffic from one crossing heading to the other crossing).
