Traffic problems on way to Killarney Racegoers heading south-west for the start of the four-day July Festival meeting at Killarney this evening would be advised to avoid the Limerick route due to a number of road traffic alerts. The alternative way via Mitchelstown and Mallow appears a better option due to problems around Nenagh and Adare. There are major delays and traffic is being diverted through Nenagh, while Adare has a stop/go system in operation from 9.30am to 4pm from today through to Wednesday.
