The truckie who casued this traffic jam faces a $2200 fine: the cost to Sydney will be $1 million THE driver of the truck that got wedged in a tunnel on one of ­Sydney's busiest motorways ­yesterday, causing traffic chaos, could be fined just $2200. The cost to Sydney is likely to be more than 450 times that - at more than $1 million. At the peak of the gridlock, commuters were caught in a 6.5km jam, snaking from the Eastern Distributor tunnel at Moore Park to the Harbour Tunnel, after the Mack truck's tray was activated, smashing sprinklers and showering vehicles in water and debris. The tunnel was closed southbound from about 8am until nearly 3pm and was due to close again at 9pm last night so more repairs could be carried out before this morning's peak. Police and Roads and Maritime investigators examined CCTV footage showing the truck, owned by Smithfield-based landscape supplier The Good Soil, approaching Moore Park with the tray ­moving into the upright position. The driver had to be freed from the cab and was treated at St Vincent's Hospital for minor injuries. A traffic queue stretched 5km southbound from the Eastern Distributor to the Sydney Harbour Tunnel. AMP chief economist Shane Oliver said the cost of the traffic snarl to the city and state's economy would likely top $1 million. Mr Oliver said when the time of the thousands late for work is added to delays in deliveries and the cost of business people missing their planes, "it will result in a ­significant loss in productivity." "This is not just one individual late for work, it has ripple effects across the economy," he said. Yesterday's incident echoed the chaos in November caused by a truck hitting the roof of the M5 East Motorway tunnel. The ­damage bill was about $250,000. A spokesman for The Good Soil would not comment yesterday. Roads Minister Duncan Gay said: "I just wish these drivers would put their brains into gear before they put the trucks into gear." Traffic was backed up for at least 5km after a truck became wedged in the Eastern Distributor tunnel.
