See how modern mega construction projects turn bridge and highway building into industrial-scale manufacturing. Watch 900-ton girders carried across completed spans, 820-ton box girders placed in a single lift, 3,300-ton marine sections installed from crane barges, and a 10,000-ton steel arch floated into position using ballast water and hydraulic jacks. The documentary also explores precast bridge factories, launching gantries, incremental launching, balanced cantilever construction, massive earthworks, asphalt paving, slipform concrete paving, chip sealing, and highway maintenance. From millimeter-precision bridge assembly to machines laying up to 1,800 tons of asphalt per hour, this is how giant roads and bridges are built, finished, and kept alive. Civil engineering on a colossal scale.
