GARDAI have launched a major investigation following a tragic accident during rush hour on one of the busiest roads in the country.
A man (64) died in the horrific accident during rush hour on one of the busiest roads in the country.
The incident occurred on the N7 Naas Road near Citywest at around 5pm.
It is understood that the man was crossing the busy dual carriageway when he was struck by a car close to Junction 3.
Evening rush hour traffic ground to a standstill, with the southbound side between Junction Two Kingswood and Junction Three Citywest closed completely up until 11pm.
Many commuters have been affected by the traffic gridlock that resulted with long tailbacks on the motorway.
The incident happened at junction 3 of the N7 Naas Road around 5pm.
The N7 has since reopened.
