The trapping of motorists underground in the M4 Motorway Tunnel during the morning peak and gridlocking traffic across the city for hours is a reminder of the vulnerability of Sydney’s infrastructure. But Thursday’s catastrophe has been compounded by the open warfare that erupted between Transurban and the Minns government over the emergency closure.

Motorists, both above and below ground, were kept in the dark for hours while authorities dithered and their failure to act cohesively resulted in a massive lack of communication to inform the drivers and commuters what went wrong and how long a fix would take. And a day later, authorities were still passing the buck and the motoring public was none the wiser.
