Holyport Interchange

Holyport Interchange is Junction 8/9 of the M4.

It is a simple roundabout interchange with the A404(M) (the rump part of the Maidenhead Bypass) and the A308(M) (a link made due to the closure of junction 8 when the M4 was extended from part-way along the existing motorway and the new junction to tie in the bypassed section was deemed too close to junction 8).

Maidenhead services would have been to the south of the junction, accessed from it.
