Luas Red Line services between Connolly and The Point will remain closed for at least the next seven days due to a fire in the docklands area of Dublin city.
In a statement, Luas operator Transdev said the significant damage meant that George's Dock bridge must undergo structural engineering assessments, multiple inspections by Luas engineering, maintenance and safety teams from Transport Infrastructure Ireland and Transdev (Luas operator), as well as essential repairs.
"Only when these works and checks are complete will services be able to resume," it said.
"At present, we cannot confirm a reopening date. Luas will continue to provide updates as progress is being made."
It added that the checks are "essential for everyone's safety, and we appreciate your patience and support".

Luas tickets are valid on Dublin Bus between Connolly and The Point for the duration of the disruption.
Dublin Fire Brigade (DFB) confirmed the large fire had been brought under control overnight on Tuesday.
An inspection of the bridge will determine when it reopens, DFB Assistant Chief Fire Officer Greg O'Dwyer said.
"The bridge was compromised last night. It's a steel construction bridge.
"It has returned to its original shape, almost, but it will have to be examined by a team of engineers from Dublin City Council and Transport Infrastructure Ireland to decide what repair works will need to be carried out and when the Luas can return," he said.
Emergency services were alerted to the incident around 6.10pm on Tuesday, with reports of a gas line on fire underneath the bridge.
Service ducts, which carry electrical and network cables under the bridge were on fire, the fire service said, adding that the cause of the fire has not been determined.
"I'm not sure whether a fire was lit underneath the bridge or whether it was the cables that compromised the gas line," said Mr O'Dwyer.
"But when the gas line went on fire, we had to boundary cool everything else, try and protect the bridge, try and protect the buildings beside it and try and tackle the electrical fire in all of the ducts."
Mr O'Dwyer said they were now handing over to the gardaí, adding that the road and the bridge will be "out of bounds".
DFB said operations were concluding at the site adding that the bridge was being assessed but remains closed.
DFB said four fire engines, a foam tender and a water tanker attended the scene at George's Dock in the IFSC.
