An exhibition featuring exquisite scale models of the world's most famous bridges is on display at the Science Museum in celebration of the opening of the Tsing Ma Bridge. Jointly organised by the British Council and the Urban Council, the 'Living Bridges' exhibition is on a world tour which will include Russia, France, Holland, Japan and Australia. It captures the design and technical wonders of bridge-building throughout history. Fifteen delicate, 1:200 scale models of the most striking bridges in the world, both real and imagined, that have been designed over the past 600 years, span a 'river of time' which flows through the exhibition gallery. Alongside Old London Bridge, the Ponte Vecchio and the Pont de Notre Dama stands two finely built models of the Tsing Ma Bridge, the world's longest dual purpose rail and road suspension bridge. One of the models shows the bridge's full span and the other, a cross-section, displays the arrangement for different modes of traffic on the two-tier bridge. 'Living Bridges' was initiated by the Royal Academy of Arts in collaboration with the Georges Pompidou Centre in Paris, and was first staged at the academy from September 1996 to January 1997, drawing a record attendance of 122,000 visitors. The models each cost between GBP3,000 (about HK$38,000) and GBP10,000. British Council director Tom Buchanan said the exhibition was the result of the council bringing two centres of excellence together to collaborate, the Royal Academy of Arts in London and the Science Museum in Hong Kong. 'These two institutions have brought us a fascinating exhibition with developments in history, architecture and technology all embodied in a building type which many people have a feeling for, especially in Hong Kong now that we see the completion of our first major bridge,' Mr Buchanan said. The exhibition ends on Sunday.
