ALL 7.5km of the new Luas Cherrywood railway track have now been laid.
The final piece of track was welded by Railway Procurement Agency (RPA) contractors on the new Luas Cherrywood Extension to Luas Green Line at the new Brewery Road Luas bridge in Sandyford this week.
Officials from Dunlaoghaire Rathdown County Council, including Cathaoirleach Cllr Marie Baker and Frank Allen, chief executive of the RPA, were on hand for the occasion.
"This is a major milestone in the delivery of Luas Cherrywood, as it concludes all track-laying activities for the full length of the 7.5km line from Sandyford to Brides Glen, including all bridges, integrated and segregated areas," the RPA said.
Cllr Baker helped in the last rail weld on Line B1, the new extension which will link Sandyford with Brides Glen.
The extension is due to open later this year.
Luas Cherrywood will extend the existing Luas Green Line (St Stephen's Green to Sandyford) to Brides Glen.
The scheme is part of the Government's Transport 21 investment programme.
Over the coming months, completion of the hard and soft landscaping works will form the bulk of the construction activity, the RPA said.
From Wednesday, all overhead electricity cables on the Line B1 extension from Sandyford to Cherrywood will become live.
"Once installed, overhead cables will be live and will remain live," the RPA said, warning people to keep clear of cables and poles.
"Some passengers will come from the bus network but a significant proportion will also come from private car and other modes of transport," the RPA said. "Line B1 will offer a real alternative transport mode for trips from South Dublin to the City Centre."
