jon, Engineering question
Denmark - when building the Storebæltsbroen - concluded you cannot easily put a railway on a suspension bridge (so tunnelled the railway instead)
The Øresundsbron is a cable stay bridge instead of suspension
And here comes a proposal for a suspension bridge at the Strait of Messina with a central span of 3.3km... how will they account for movement / flex when a train crosses? 🤔
