Construcción de puente en Timelapse sobre el río

Timelapse video from a fixed wide camera, both banks bracketing a slow river in the middle ground. Survey boats scatter buoys; excavators clear abutments; barges nose in with steel cofferdams. Water is pumped back; foundations bite deep; rebar skeletons thrust upward. Piers climb in stepped pours; cranes swing girders into place, locking the two shores closer span by span. Falsework sprawls like scaffolding over water; deck slabs ripple in concrete waves; parapets and guardrails crest along the edges. Cables sling down in silver arcs; anchors clamp. Asphalt unrolls in black ribbons; lane stripes flicker in fresh paint. Lighting poles spark on in sequence, mirrored in the river below. At last, cones sweep aside and headlights stream from both banks - cars and trucks flowing across, the bridge binding land to land in one continuous line.
