So this is a copy of the variation that included the park and ride in the development plan. Its not online on the Cork County Council website for some reason - maybe this is why the NRA missed it.
The variation modifies both the overall county development plan and the local development plan, hence it is in two parts.
There are two issues:
1. It is really difficult to make the interchange freeflow without the site suggested for the park and ride.
2. The access to the site suggested for the park and ride is problematic:
a. It can't come off the existing roundabout as it is already overly busy.
b. If the interchange is upgraded the park and ride still won't have access as any potential access will be designed out to make the interchange freeflow.
Neither of these is fatal, as you could access the park and ride from the local roads, but it does make the P&R car park rather complicated with two slip roads running through it and another two elevated slip roads over it.
I also attach a drawing with a suggested layout for the interchange upgrade. The design would probably need to be quite close to this if it is to be fully free-flowing. The main problem arises with the slope down to the tunnel, which prevents the layoutt from being mirrored. The P&R site is outlined in white.
