There has been talk about it for a couple of years now. Think I read about it in a post by someone on here. If I recall there was a link to a newspaper item.
The Black Ashe park and ride is very useful for visiting Cork. I find the staff very helpful. If you do want to use it, the entrance has a height barrier, so drive up to the bus entrance. The guys will open the barrier for you they generally get Motorhomes to park near the fence on the left after you have driven in past the terminus.
