I don't see why they couldn't have done what they've done at junction 30 with the other end of the A4232. Build a dual carriageway from junction 33 to Llantrisant road and then build the village to the west of it. That way it's there for future developments, provides access to the village and better access to Creigiau and Pentyrch. As it stands There's still pretty shit access to the M4 for those villages, which is pretty daft when there's a junction right next to them.

Pontprennau may be shit in some respects but at least it's very accessible by car and likewise, because of previous planning, so will St Edeyrn

The "Echo" has missed this point completely, its report stating there will be access at Junction 33. I agree with George this looks like a form of nimbyism. Still, it will be interesting to hear the complaints from the new residents when they are stuck in gridlock.
