A NEW scheme to ease traffic congestion on the Island Eastern Corridor is showing early signs of success, according to the Transport Department, district board members and the Automobiles Association. One Eastern District Board member said the corridor diversion had lopped up to 30 minutes off travelling times for motorists crossing the harbour. Under the pilot scheme, which began last Sunday, motorists taking the slip road on Man Hong Street are banned from entering approach lanes to the Eastern Harbour Crossing. The diversion means an extra five to seven minutes for motorists. In the past, traffic became jammed as drivers waited to merge with vehicles on the approach lanes to the tunnel after driving up Man Hong Street. Chairman of the Eastern District Board's traffic and transport committee, which initiated the scheme, Wong Kwok-hing, said he was pleased with the initial results. Hong Kong Automobile Association chief executive Kendy Chan Kin-chung agreed traffic had improved but said the scheme would really be tested after the summer holiday, when traffic volume would increase dramatically.
