🇨🇭🏗️ Switzerland built a 240-meter mobile bridge so highway traffic never stops during roadworks… The ASTRA / FEDRO Bridge lets cars and heavy trucks drive overhead at speeds up to 60 km/h. Construction crews work completely sheltered underneath without daytime lane closures or detours. The entire structure lifts and advances remotely along the highway as paving sections finish. Shields workers from fast-moving traffic while keeping major commuter arteries flowing freely. Should every major country implement mobile construction bridges on busy highways? What are your thoughts? 🤔💭 ( Media: Federal Roads Office FEDRO ) #switzerland #engineering #construction #highways #infrastructure
