The Strait of Messina Bridge would connect Sicily to the rest of Italy over a 2-mile stretch. It's expected to cost 13.5 billion euros ($15.7 billion), which Italy's Presidency of the Council of Ministers says will be completely funded by the public and has already been accounted for in the 2024 and 2025 budget.

Rome has given final approval to a €13.5bn ($15.6bn) project to build the world's longest suspension bridge, connecting the island of Sicily to the region of Calabria, on the tip of Italy's boot. The designers claim the bridge – which is due to be built on one of the most seismically active areas in the Mediterranean – will be able to withstand earthquakes.
