The Italian government has approved the construction of a suspension bridge between the island of Sicily and the mainland. It would be 3,300 metres long and 400 metres high. The bridge has been designed to allow nearly 140,000 vehicles to cross it every day. This colossal project, estimated to cost €13.5 billion, has been presented by Rome as a strategic asset for NATO defence. But the initiative has received much criticism – those who oppose the plan see it as a costly waste of public funds.
