Harbour advisers have suggested the government review the designs of a bridge and a helipad planned at the tip of the Kai Tak development to give the public more access to the harbourfront. The proposed bridge, which would connect the runway of the former airport and Kwun Tong, could become an eyesore taking space away from a future park on the runway, said Vincent Ng Wing-shun, a member of the government's Harbourfront Commission. The architect said the bridge's anchor points must stand on the two sides of the channel and not on the seabed, given reclamation in the harbour was not allowed anymore. 'The bridge must be built high enough to allow barges to pass underneath. This means the ramps on both sides would have to be several storeys high, swirling like spaghetti before reaching the ground,' Ng said. Paul Zimmerman, of the Society for Protection of the Harbour, agreed that the bridge would take up some beautiful open space at the runway. The society is member organisation of the Harbourfront Commission. Both men were expressing their individual views. The Kai Tak development into a cruise terminal, and residential, commercial and community facilities covers more than 320 hectares and will be completed in three phases in 2013, 2016 and 2021. Concern over the layout was also expressed at a meeting of professionals from a committee that advises on bridge designs earlier this week. An engineer said the bridge, carrying vehicles and pedestrians, would be too bulky for the 400-metre wide channel. One way to slim down the design would be to build it solely for pedestrians, said structural engineer Dr Greg Wong Chak-yan. Another option was to have a bridge that could be raised up for specified times for barges, which would allow facilities such as a hospital or waste treatment works, to use the channel, Wong said. Residents from Kwun Tong have strongly demanded a bridge so they can easily get to the future centre of Kowloon. The district would also be linked to Kai Tak by monorail, although the journey would take a few minutes longer than by using the bridge. Kwun Tong District Council chairman Bunny Chan Chung-bun said the council was open to discussions if the bridge had drawbacks. A footbridge would be acceptable as long as it had an iconic design, he said. Commission members, however, are split about the location of a helipad, also planned at the tip of the runway. Ng said the site should be accessible to the public and not fenced off for the cross-border facility. Government planners are studying the possibility of relocating the helipad to the rooftop of a 100-metre observation tower nearby, but this would confine the use of the helipad to the more costly double-engine helicopters.
