Design sturdy bridges across canyons, rivers, and construction sites using wood planks, steel beams, and high-tension cables. Limited budgets and awkward anchor points force creative engineering; place trusses too sparsely and your truck plunges, overbuild and funds run dry. A real-time stress overlay highlights weak joints, encouraging iterative refinement until the vehicle rumbles safely across. Later scenarios add hydraulic lifts and explosive barrels that demand even smarter load-balancing solutions.
