Tunnelling project faces delays

A massive tunnelling infrastructure project is facing delays after workers were evacuated twice in a week following safety incidents.

New South Wales’ WestConnex project – which will provide a connection for motorists between the upgraded M4 and M5 motorways, and to Port Botany, the airport and the M6 – is facing delays after a generator failure and a burst pipe.

More than 300 workers were evacuated from the tunnels following power issues, the second delay for the week.

The first incident requiring more than 200 electricians to down tools after raw sewerage overflowed from a portable toilet block into the tunnel.

The WestConnex project is being financially supported by a AU$1.5 billion grant from the Federal Government and AU$2 billion concessional loan to the NSW Government.

Work on the M4-M5 Link started in 2018 and the new M4 tunnels are anticipated to open in 2019.
