TRAFFIC police and container terminal operators have braced themselves for a surge in the number of truck drivers trying to make deliveries to Kwai Chung before the holiday weekend. For the first time an emergency traffic control centre is being manned even before a major traffic jam has developed. The most likely time for a jam is during this evening's rush hour as thousands of cars passing through Kwai Chung mingle with container trucks, police said. Senior Superintendent Traffic New Territories South Harry Razack said: ''We are keeping our fingers crossed it does not happen, but we have to be prepared for every eventuality.'' Mr Razack said police were expecting at least 2,000 extra container trucks to make for the port. ''We know that because of the typhoons hitting Taiwan recently a number of ships have been delayed and rescheduled for the end of the month.'' Extra traffic was also expected as factories in China rushed to meet their deadlines for Christmas goods, while drivers might also be trying to get their work finished before the bank holiday. The peak period for goods traffic would be between 10 am and 6 pm as drivers came south after the border opened and headed north before it shut, Mr Razack said. But congestion would probably be worse in the evening. ''In the evening hundreds of thousands of cars will be using Kwai Chung Road. There will be very heavy traffic,'' he said. The traffic would also be restricted because of the continued disruption from landslides on Castle Peak Road. ''Although the road was [earlier] open to single lane traffic at the 141/2-milestone a lot of people will not want to wait at the lights and will go by Tuen Mun Road instead.'' A spokesman for Modern Terminals said although they did not expect a substantial upsurge in traffic, extra staff would be on duty.
