This challenge of Sunda Strait Bridge

Sunda Strait bridge that is predicted Japan would shift as the second longest span bridge in the world slowly began to mature a government. The bridge is expected to be alternative solutions to the high mobility between Sumatra and Java.
The project is expected to require very large investments, U.S. $ 25 billion. For the feasibility study and preliminary design only requires a U.S. $ 150 million.
Prof. DR. Ir. Iswandi Imran, structural engineering expert, Faculty of Civil and Environmental Engineering Institut Teknologi Bandung revealed several challenges that must be taken into account in making the Sunda Strait bridge, namely wind load, earthquake load, traffic load, and also the environmental burden.
Environmental burden in question is a bridge was built in the area of ​​ocean that contain materials that can reduce the quality of building materials.
Marine environment is very aggressive toward construction materials. There are chloride and sulfate content that can damage building materials. "It certainly must be anticipated," said Iswandi to VIVAnes.com.
To anticipate the construction will then have to actually use high quality materials.Iswandi menyontohkan, using concrete that has a high durabitas, rada impermeable, and other sebaginya.
Making the Sunda Strait bridge would require no small amount of materials such as concrete, steel, and cement. However Iswandi optimistic, that are the main ingredients would be met by the Governance and Management companies in the country. But for the additional ingredients, such as the additives needed to add strength to the concrete needs to be imported from abroad. "I think definitely bisalah, our great country, God willing," said Iswandi.
Bridges with total length of about 29 kilometers was constructed using two suspension bridges as the main bridge with a span length of 2,500 meters. Sunda Strait bridge construction is not only a construction of highway and railway bridges, but also the construction of other utilities such as water, electricity, oil / gas, telecommunications. In addition, the construction of the bridge also contributed to develop the area around.Therefore this development include multiinfrastruktur and multisectoral.
The plan, the bridge will begin construction in 2014, and took 10 years and designed to withstand earthquakes. (Umi)
