An elderly woman was killed while apparently trying to cross four lanes of traffic on a busy dual carriageway in south Dublin.
The incident happened shortly before 1pm yesterday on the N11, near Cabinteely Village.
Her body was discovered in one of the south-bound lanes of the road.
Gardai are trying to establish how the woman, who was aged in her 80s, died. She was declared dead at the scene.
Her body has been taken to Saint Columcille's Hospital, Loughlinstown, where a post-mortem was to be arranged last night.
It is understood that the victim may have been struck by a car. The crossing at the junction is served by a footbridge which traverses all four lanes on the road.
Officers closed off the road and the footbridge yesterday for an investigation.
Local Fine Gael councillor Barry Ward said that the incident was a shock to the whole community.
"Whatever happened it's a terrible loss of life," he said.
He added that Dun Laoghaire-Rathdown County Council had only recently agreed to upgrade that section of the road.
One witness described how he was caught up in the traffic while the road was closed.
"I could see her body lying on the road, just in front of the footbridge," he said.
Witnesses have been asked to contact Dun Laoghaire Garda Station on 01 6665000.
Meanwhile, gardai in Co Tipperary are investigating a fatal crash which happened on the N24 Limerick to Waterford Road at 1pm.
A woman in her early 70s was struck by a lorry and pronounced dead at the scene.
Witnesses are asked to contact the gardai in Clonmel on 052 6177640.
