Overheight truck closes M5 citybound tunnel Roads and Traffic Motor News NSW Motorists are being urged to stay away from the M5 East tunnel after an oversize truck caused significant damage to it on Thursday morning. There is no forecast as to when the tunnel will be repaired, the Transport Management Centre says. There were reports that the truck had ripped a lot of the infrastructure from the ceiling of the tunnel. Just before 9am, traffic was queued for 12 kilometres back to Henry Lawson Drive. At 9am, all westbound lanes of the tunnel were open but the citybound tunnel was closed Motorists are being diverted on to King Georges Road, Stoney Creek Road, Forest Road, Wickham Road and Marsh Street, and buses through Kingsgrove are delayed. A steady string of overheight trucks have been stuck in Sydney's tunnels recently, worsening the city's already crippling peak-hour traffic. This has happened despite Roads Minister Duncan Gay introducing new fines and suspensions for trucks damaging tunnels. Penalties of $2200 and six demerit points apply for driving overheight trucks into tunnels. But from June it became easier for the government to pursue the companies that own the trucks for the cost of repairing the damage. In addition, trucks that get stuck will have their registrations suspended for three months. with Amy McNeilage
