A tanker carrying diesel overturned yesterday, closing a vital east-west Kowloon link and causing traffic mayhem. Vehicles were brought to a standstill from about 2 pm as thousands of litres of fuel spilled from the tanker. Diversions were brought into force as sections of Ching Cheung, Tai Po and Lung Cheung roads were closed for about three hours. Police said the spill was near the site of a landslip which closed Ching Cheung Road for three weeks in August, causing traffic chaos. The three-axle lorry was heading east on a steep section of Tai Po Road when it lost control and overturned close to where the carriageway merges with Lung Cheung Road. Police said the driver, believed to have been contracted by oil giant Mobil, was slightly injured. They added the fuel was flowing down the bitumen like a stream. 'There was diesel everywhere, all flooding down the carriageways and into the sewers,' said senior inspector Paddy Healy of Kowloon West Traffic. 'The whole area was covered in diesel, all very greasy and slippery.' Urban Services Department staff diluted the fuel with soapy water and shovelled sawdust on to the road to provide grip.
