Ravensburger GraviTrax Extension Bridges

Ravensburger GraviTrax Extension Bridges – Expand Your Marble Run

The GraviTrax Extension Bridges set is a building expansion for the Ravensburger marble run system, designed to extend track layouts with sturdy bridge structures.

• 14 pieces provide enough components to build multiple bridge extensions across a marble run layout
• Compatible with all GraviTrax track systems, allowing seamless integration with existing starter sets and expansions
• Sturdy plastic construction ensures stable bridge structures that support the marble track reliably
• Recommended for children aged 8 and up, offering an age-appropriate building and engineering challenge

What makes GraviTrax Extension Bridges special

Unlike standard track pieces, the extension bridges add vertical clearance and structural variety to a marble run. The 14-piece set gives builders the flexibility to create multi-level layouts where marbles travel over gaps and obstacles, increasing both the visual complexity and the mechanical interest of the track.

Ideal for...

Young builders aged 8 and up who already own a GraviTrax starter set and want to expand their track layouts with new structural elements. The bridge concept introduces engineering thinking — planning clearances, supporting track segments, and designing routes that incorporate vertical drops and crossings.

Application of GraviTrax Extension Bridges

1. Connect bridge pieces to existing GraviTrax track segments to span gaps between platforms or tables
2. Combine multiple bridge sections to create multi-level marble run structures
3. Experiment with different bridge configurations to alter the marble's path and speed
4. Integrate with other GraviTrax expansions such as loops, curves, and launch pads for a complete custom layout
