Indonesia will begin the construction of a giant sea wall that will stretch hundreds of kilometers along the nation’s main Java island to prevent flooding and coastal erosion, President Prabowo Subianto said.

The sea wall is estimatedBloomberg Terminal to cost $80 billion and take about 20 years to build, Prabowo said in a speech to investors at the International Conference on Infrastructure in Jakarta on Thursday. It will span at least 500 kilometers from the island’s westernmost city of Banten to the Gresik regency in East Java.
