Commuters have to wait an aver age 56 minutes to cross the Lok Ma Chau border, an 'unacceptable' amount of time, the DAB says. In a survey by the Democratic Alliance for the Betterment of Hong Kong, 22.5 per cent of the 510 respondents said they had waited for more than two hours when they crossed the border from Lok Ma Chau to Huanggang by shuttle bus during the four-day Easter break. Lawmaker Lau Kong-wah said the shuttle bus journey normally took 25 minutes, adding he thought it would be unacceptable if passengers had to wait nearly an hour to cross the Lok Ma Chau border. Mr Lau urged the bus company to add another two buses to the current 10. The legislator also recommended extending the operating hours of the border and shuttle bus service, as 38.8 per cent of respondents to the survey said they would choose the shuttle to avoid the congestion at Lowu. Lok Ma Chau operates from 7am to 10pm, while Lowu opens from 6.30am to 11.30pm. Mr Lau said an extension in working hours would help relieve the burden on Lowu. Mr Lau has submitted suggestions to the Immigration Department, but the department said the limited space at the border might rule out more buses.
