Cable Girder Crossing

Cable Girder Crossing is a 60 FPS 2D valley bridge construction simulation
built around escalating multi-tier vehicle and freight train load tests.

Span deep mountain gorges using reinforced road-rail decks, timber bracing,
heavy steel box girders, high-tensile stay cables, and granite-anchored
concrete support pillars. Every span must withstand three consecutive load
tiers: commuter cars, armored semi-trucks, and a massive diesel freight train.

Features:
- Real 60 FPS truss and pillar compression physics with live axial stress heatmaps
- 5 structural elements: Road-Rail Deck, Timber Strut, Steel Girder, Stay Cable, Concrete Pillar
- Escalating 3-wave load certification per crossing: Cars -> Heavy Trucks -> Cargo Train
- 3 valley chasm stages plus Casual, Arcade, and Turbo difficulty modes
- Real 16-bit PCM WAV audio, persistent high scores, CSV export, and EN/VI UI
