Up to 400,000 people are expected to flock to the Tsim Sha Tsui waterfront to celebrate Christmas and New Year but the areas might reach maximum capacity well before midnight because of the fireworks displays and the light shows in Victoria Harbour, police have warned. Yau Tsim district's deputy district commander, So Kam-sing, said that police expected a turnout similar to last year at the area near the clock tower and Cultural Centre. Christmas Eve and New Year's Eve both fall on Sundays this year. However, police said they expected an early first wave of revellers flocking to the area from around 6.30pm, well ahead of the 'Symphony of Lights' at 8pm. The laser lights show, which takes place every night on both sides of the harbour, will be enhanced with new fireworks displays from tomorrow to Christmas Day and again from December 30 to New Year's Day. 'We might need to stop people from getting into the area as early as 6.30pm if the area reaches a maximum capacity of 120,000,' assistant district operations officer Patrick Yeung Ming-sum said. 'The restrictions will be eased when some people leave after watching the light show - before we close the area again before midnight.' Some 1,400 officers will be deployed for traffic and crowd control. Roads will be closed and traffic re-routed on Christmas Eve and New Year's Eve. The southern part of Nathan Road and Cameron, Hankow and Peking roads will be closed in stages from 5pm. Traffic towards the area will be diverted to Jordan, Hung Hom and Tsim Sha Tsui East. With a number of road works and construction projects under way in the area, police have urged the public to be careful and not to climb fences to get a better view. The police will team up with the Food and Environmental Hygiene Department to crack down on illegal hawkers. As in previous years, thousands of people are expected at the New Year countdown at Times Square in Causeway Bay. Roads leading to Times Square will be closed. Sections of Lockhart and East Point roads and Great George Street will be turned into pedestrian zones from 4pm to midnight tomorrow and noon to midnight on December 24 to 26 for the crowds attending the 41st Hong Kong Product Expo in Victoria Park. The Lan Kwai Fong area is also expecting a flood of revellers, with Lan Kwai Fong and nearby D'Aguilar Street and Wing Wah and Wo On lanes turned into pedestrian zones from 5pm on December 31 to 6am on New Year's Day. Guy Lown, chief inspector for traffic on Hong Kong Island, said sufficient manpower would be deployed to handle the crowd but he advised parents not to bring small children to the area. The MTR Corp and Kowloon-Canton Railway Corporation will provide round-the-clock services on most of lines, while bus and ferry companies will boost services on Christmas Eve and New Year's Eve.
