It is a suspension bridge with a 41-meter-wide deck carrying six lanes of automobile traffic and a lower level with two rail tracks.[1] At completion it was the world's second-longest span suspension bridge.[2] Tsing Yi and Ma Wan islands are linked by the Tsing Ma Bridge in Hong Kong.[2]
Geography and history
Gammon Construction built the caissons for the bridge towers, floating each framework into place and filling it with concrete underwater.[3][4] On the Ma Wan side, each of the two caissons has a weight of 4,500 tons; the two caissons on the Tsing Yi side are each approximately 3,000 tons.[4] During the latter part of 1994, the initial steel deck segment was positioned by lifting.[5] By May 1997, construction had been completed.[6]
Margaret Thatcher, a former British Prime Minister, officiated the inauguration of the Lantau Link (which includes the Tsing Ma Bridge) on 27 April 1997.[6] Over 100,000 people watched the opening ceremony, which featured a fireworks show lasting 20 minutes and costing HK$5 million.[7] At 8:00 am on 22 May 1997, the Lantau Link was opened for traffic.[8]
What the cited sources add
The same article noted that 300,000 people were expected to descend on Tsing Yi Island and the Castle Peak coastline for the fireworks.[9] A 2017 South China Morning Post article by Stuart Heaver stated that the bridge is eight metres higher than official records show, meaning mega-ships have been needlessly prohibited from using the Ma Wan channel for years.[10] That article reported that a special technical report dated November 1, 2016 found the height discrepancy.[10]
