|Aust Interchange • Newhouse • Rogiet Interchange|
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).
