PolyBridge Construction

PolyBridge Construction is a realistic bridge-building simulator that challenges your engineering, creativity, and problem-solving. Plan designs in a simple 2D interface, then switch to 3D to test bridges under live vehicle loads — from cars to heavy trucks. Build with steel, wood, and steel rope, watch color-coded stress feedback, and iterate until your structure holds.

Designed for players who enjoy puzzles and structural thinking, the game features 32 increasingly difficult levels, detailed environments, and a realistic physics engine. Drag materials, connect joints, and test your solutions — analyze tension, fix weak points, and optimize balance and load capacity to master each span.
