Amazing Bridge Transformation | From Old Wooden Bridge to Modern Arch Bridge | Full Construction Process.
Watch the complete transformation of an old wooden bridge into a modern two-lane steel arch bridge.
The project begins with the demolition of an aging wooden bridge, followed by site preparation, foundation excavation, PCC placement, waterproof membrane installation, heavy rebar cage assembly, and large-scale concrete foundation construction. Abutments, wing walls, bearing pedestals, and bridge bearings are then completed to support the new structure.
Massive steel arch ribs are erected and connected with cross-bracing systems, followed by vertical hanger cable installation, longitudinal girder placement, and bridge deck construction. Approach roads are developed using selected granular fill, grading, and compaction. Prime coat and tack coat applications prepare the roadway surfaces, while waterproofing systems are installed on the bridge deck before asphalt paving and final compaction create a smooth driving surface.
The finishing stages include steel guardrail installation, pavement markings, roadway lighting, and protective anti-corrosion coating of the steel arch structure. Final inspections and site cleanup prepare the bridge for service.
The video concludes with the completed bridge opening to traffic, showing vehicles crossing the new structure from daytime through nighttime. From demolition to final operation, this video captures the entire process of replacing an old wooden bridge with a modern steel arch bridge.
