A man killed in a ten-vehicle crash on Sydney’s M4 motorway this morning was an Irish tradesman on his way to work.
All four citybound lanes and one westbound lane were closed after the crash on the approach to Church Street in Mays Hill at 5.50am.
The man, a 36-year-old Irish national, died at the scene and five others were taken to hospital with non-life threatening injuries.
All of the drivers will undergo mandatory blood and alcohol testing.
Traffic drew to a standstill and was queued back as far as 15km citybound.
One citybound lane has since reopened but traffic remains heavy.
There are lengthy delays, with motorists told to consider using the Great Western Highway and re-joining the M4 at James Ruse Drive.
The Burnett Street eastbound on-ramp is also closed.
Commuters are also urged to use the train network where possible.
“Due to the serious nature of this crash, there is no forecast as to when all lanes will been reopened,” a Transport Management Centre spokesman said.
