How to build a bridge

Drag from an anchor (the amber pins on the banks) or from any joint to draw a member. Members snap to a 0.5 m grid.
Lay a road deck from bank to bank. Only road carries wheels.
Brace it with triangles. A deck on its own sags and snaps.
Test it. The vehicle drives across. Members glow hot as they near failure, then break.

Engineering truths in the game: long members in compression buckle (capacity falls with 1/L²). Cables only pull. Forces view shows tension in red and compression in blue.
