Saved Design Projects — click one to open its tools; new work joins the open design
Every project starts as a named design — new roads and reconstruction (levels, direction, demolition). Start one, draw into it, then finalize & bid it in Jobs. Place a Start first.
Your built assets — a construction yard for crews & equipment, a retention pond as a drainage outfall, plus roadside placements: traffic signals, toll booths and trees.
See how the network is flowing — the congestion heatmap and busiest destinations, and road conditions with a wear forecast.
Terrain style — texture the map to your liking; the terrain itself never changes
See how your network is doing — and raise money for the next project.

⚓ Port
Passing ships pay a docking fee you collect. Bigger ships need a bigger port — and a tall enough bridge to reach it.

🚗 Traffic
Roads glow green → red by congestion. Below: where trips are ending today — the places worth prioritising.
Busiest destinations (arrivals today)
Tip: click any car to see its destination as a red pin.
🛣 Road conditions
Pavement is colored good → failing by wear. The forecast estimates, at current traffic, how long before potholes break each road down.
Worst roads first
Tip: click a road below to jump to it. Repair worn lanes (Design → Repair) before they fail — a FAILED lane wrecks cars, and left long enough the whole road closes.

🏢 Today’s market — three firms bidding for your business; a new slate every day
Every firm is different: caliber (their people’s stars), a competitive edge (hover the badge), and contract terms — retainers bid cheap but cost a buyout to release early, at-will firms charge a premium. Paid daily; miss payroll twice and they walk.

🌉 Bridge Designer
Place piers, set each span’s type, and keep every span’s load under 100%. The curve under each span is its bending moment — taller & redder = closer to failure. Shorter spans (more piers), a stronger type, or a lower speed limit all add margin.

Pier—
Tip: click a span to select it, click & drag a pier to move it. A pier can’t stand in the deep navigation channel — that gap must be spanned (or use a drawbridge).
