The Minister for Transport, Martin Cullen, has signed an order giving the go-ahead for the start of work extending the Luas Green Line from Sandyford to Cherrywood in Dublin.
The extension, which will be 7.5km long and is due to be completed by 2010, is being co-funded by the Exchequer and a group of private developers.
It is expected that the extension will increase the number of passengers on the Green Line from more than 10 million a year to more than 18 million.
