Corbally is in Limerick, once you cross the bridge over the Shannon you are in Shannonbanks (imaginative name) Co.Clare. But anyway - its not that far from the station the traffic can be desperate especially rush hour but a taxi shouldn't set you back too much. You could get the bus from town if you wanted, the Corbally bus leaves from behind Arthurs Quay (5 mins from the station if you aren't carrying much!) a few times an hour.
hope that helps!
