3D Bridge Detail DWG with Steel Arch Truss and Laminated Wood Design

This AutoCAD DWG file presents a complete 3D bridge detail model featuring a steel arch truss structure placed over a contoured terrain block. The main span appears to be approximately 35m to 40m long, constructed using iron and steel truss elements arranged in a crisscross pattern for load stability. The arch ribs are modeled in red, while the secondary bracing members and deck framing are displayed in grey, giving a clear material distinction. Laminated wood components are applied along specific deck or walkway areas, combining strength and aesthetic value. The model also includes end supports, slope transitions, and foundation contact areas for realistic structural visualization.

The exported 3D geometry provides an accurate representation of how the arch ribs transfer forces into the deck and side supports. The terrain block showcases cut and fill areas, enhancing understanding of site integration. This DWG file is useful for architects, civil engineers, and infrastructure designers who need a ready-to-edit 3D model for analysis, visualization, or presentation work. The model supports workflows in AutoCAD, Revit, 3D Max, SketchUp, and rendering engines, making it suitable for conceptual engineering studies, bridge form evaluation, and design development.
