A critical crossing is the closest thing to a true monopoly in infrastructure — one structure, no competing route for miles, and a charge on every vehicle. Pick a real asset below and follow it through the map, the business model and a working returns model.

Drag the sliders to see what crosses the bridge — and what it earns.
The owner keeps the toll and takes the traffic risk: revenue is whatever crosses, times the toll. Upside is uncapped if traffic grows, but a soft economy or a new competing route bites directly. Tariffs are usually inflation-linked and the crossing is a near-monopoly, so demand is famously inelastic — which is exactly why investors pay the highest multiples for a critical toll bridge.
