The NSW Government will be crossing its fingers peak hour traffic runs to time today, after yesterday’s M5 meltdown.
The M5 East Tunnel has been shut since midnight, as engineers try to get to the bottom of the computer glitch which brought Sydney's south to a grinding halt.
It's open now, but the fear for tens of thousand of motorists stuck in yesterday's traffic chaos, is that the meltdown could happen again.
This is the fifth time a computer malfunction has forced the tunnel to shut since the road opened in 2001.
Roads Minister Eric Roozendaal says the government is determined to get to the bottom of the issue.
“Yesterday we had a computer crash and the back up computer also crashed.
"That’s why the government believes it’s important that we commission an individual audit of systems on our critical paths and road infrastructure, to ensure the back-up systems and electronic systems are operating appropriately.”
And although the State Government tried its best to wash its hands of the issue yesterday, blaming the tunnel's private operators, it comes on top of other transport woe this week.
This week also saw the breakdown of the spit bridge and safety concerns with 80 new bendy buses.
