A week ago, the Chinese government opened the Jiaodhou Bay Bridge, linking the port of Qingdao to the island of Huangdao. Built in four years, the colossus of the sea is 42 kilometers long and cost the equivalent of US$ 1.5billion A week ago, DNIT chose the design for the new Guaíba Bridge in Porto Alegre (BRAZIL), one of the promises of the then candidate Rousseff. Entrusted to the Ministry of Transport (BRAZIL), the colossus of the river should be ready in four years. With a length of 2.9 km, it will swallow US$ 1.0billion. Intrigued, the mathematician gaucho Gilberto Flach decided to establish some comparisons between the Chinese Jiaodhou Bridge and the Brazilian Guaíba Bridge. In the Monday edition of the Zero Hora newspaper published astonishing numbers summarized in the table below: [TABLE] [TR] [TD] [/TD] [TD]China [/TD] [TD]Guaiba [/TD] [/TR] [TR] [TD]Length: [/TD] [TD]42 Km [/TD] [TD]2.9 Km [/TD] [/TR] [TR] [TD]Total Cost: [/TD] [TD]US $1.5 bil [/TD] [TD]US $1.0 bil [/TD] [/TR] [TR] [TD]Cost p/km: [/TD] [TD]US $35.7 mil [/TD] [TD]US $345.0 Mil [/TD] [/TR] [TR] [TD]Construction Time: [/TD] [TD]4 yrs [/TD] [TD]4 yrs [/TD] [/TR] [TR] [TD]Construction Time p/km: [/TD] [TD]35 days [/TD] [TD]503 days [/TD] [/TR] [/TABLE] The numbers shows that if the Guaíba Bridgewere being constructed in China, it would would be completed in 102 days, at acost of R$ 170 million. If the Jiadhou Bridge had been constructed in Brazil,the bridge would have had no completion date and would be calculated in theTrillions.
