Kilometer arch rib dragon, initial appearance of canyon bridge skeleton #infrastructure #mountains

Deep in the canyon, the construction of a super arch bridge is underway! Tens of thousands of steel bars and steel arch ribs interweave to form the "skeleton" of the bridge. A single arch rib weighs 150 tons and is precisely lifted by a cable crane, with a splicing accuracy controlled within 2 millimeters. The main arch span exceeds 300 meters, and the bridge deck is over 200 meters away from the river surface. After completion, it will become a key node for regional transportation, and each set of data is breaking new heights in bridge construction in mountainous areas! #Super Engineering #Large Projects #road #railway #expressway #construction #amazing #amazingview #unbelievable #infrastructure #building #engineering #mountains #shorts
