Truss Bridge Generator

With the power of Geometry Nodes, the Truss Bridge Generator streamlines bridge modeling in Blender, making it easier than ever to create detailed, customizable structures. This procedural tool allows you to generate truss bridges with full control over length, width, trusses, abutments, and piers. Designed for realistic infrastructure projects, it saves you time while ensuring accuracy and flexibility—an essential asset for any 3D artist.

How to Start

Insert a Bezier Curve, set the desired bridge length, and change its handles to Vector for a straight line. Then, apply the Truss Bridge Generator modifier in the Modifier tab.

Fully Procedural

The bridge geometry is generated procedurally, allowing for full customization while maintaining excellent performance and flexibility.

Customization and Features

Easily adjust the length, width, and height of the truss bridge. Abutments and piers can also be modified to match your specific project needs.

Roadway Panel Options

• Modify road width and footpath width easily.
• Set the number of lanes based on the road width (e.g., 7 meters = 2 lanes).

Truss Panel Options

• Control the width, depth, and height of the trusses.
• Split the bridge into equal segments using the sub-bridge option.
• Control the number of bays for realistic truss angles (ideally 30–60°).
• Create a Pony Truss by disabling top bracing.

Abutment and Pier Settings

• Choose pier type and foundation using the Pier Index and Base Index.
• Adjust abutment and pier height offsets to fine-tune elevation.

Additional features include traffic lighting controls and multiple railing styles to suit different bridge types.
