The Italian government plans to connect Sicily and mainland Italy with the world's longest suspension bridge.

The Ponte Stretto Messina's actual span – the section between its two supporting towers – will be slightly shorter at 2 miles. It will stretch over the Strait of Messina in southern Italy and accommodate three road lanes in each direction, two service lanes, plus two railway tracks.

The width of the bridge's deck will measure approximately 200 ft and its two ground-based towers will reach a considerable 1400 ft in height

Linking Sicily to the Italian mainland is a plan that dates back millennia, but there are good reasons that it has never actually happened. The area is very busy with shipping, it experiences high winds, and it's one of the most seismic areas of Europe.

The Ponte Stretto Messina is expected to be completed in 2032, however, as the BBC points out, there may be some opposition from local groups, which could potentially delay the start of the project. Its budget is estimated at $15.7 billion.

Bridge safety is quite a sensitive subject in Italy, particularly since the 2018 collapse of the  Morandi Bridge  https://justacarguy.blogspot.com/2022/01/if-you-recall-2019-bridge-collapse-in.html
