A burst water-main is causing traffic chaos at Newlands Cross.
This is the second time in less than a week that a water main has burst on this stretch of the N7.
Roadworks are being carried out to get rid of the last set of traffic lights between Dublin and Cork.
Three lanes outbound have reopened but inbound drivers are being advised to use other routes until tomorrow.
The leak means people in and around Clondalkin Village may have reduced water, or none at all.
