Longbridge Island

Longbridge Island is the location of a major interchange between M40 and A46 in Warwickshire. It originated as a junction between A46 and A41, and construction of a bypass for the roundabout is currently under construction.

Umberslade Interchange

The Umberslade Interchange is a triangular junction between M42 and M40 towards London. Priority is given betwen M40 and M42 westbound, with traffic wishing to remain on the M42 having to turn off. This junction would also have been the northern terminus of the unbuilt Strensham - Solihull Motorway.
