Luas track has started being laid on O'Connell Street in Dublin today.
Preparation works for the Luas Cross-City line have been ongoing since August.
The College Green bus corridor has been in operation from 7.00am to 7.00pm since August 10th, as part of traffic restrictions.

According to the Irish Times, the tracks will be welded into place on the median of the street.
Roadway works are expected to stop on November 27th to avoid disruption over Christmas.
However, other works will continue north of The Spire.
The Cross-City Luas will cost about €368m, and is due for completion in 2017.
It will connect the existing Green and Red Luas lines, and will see an additional 10 million passenger journeys per year.
There will be 13 new stops - with eight of these in the city centre area - and it will take 21 minutes to travel from St Stephen's Green to Cabra.
