Crossing Rivers in Days, Not Years

Rivers stopped most armies. Romans crossed them in days.
The pontoon bridge:

Wooden boats lashed side by side across river
Thick planks laid on top (roadway)
Weight distributed across boats (buoyancy supports entire legion)
Anchored with ropes + iron stakes (prevents drifting)
Flexible connections (moves with current instead of breaking)

Construction time: Days (vs. years for stone bridges)
Famous example: Julius Caesar crossed Rhine in 10 days (55 BC)—40,000 soldiers
Romans didn't fight the river. They worked with it.
Physics over force.
