One-way by design
Every road carries traffic only in the direction you draw it. Return traffic needs another path.
Free browser puzzle game
Traffic is easy. Until every road is one-way.
Draw roads anywhere. Merge lanes together. Bridge over problems. Then release the cars and find out whether your beautiful highway actually works.

The challenge
Draw first. Regret it later.
Highway Doodles gives you destinations and traffic demand. Everything between them is your problem.
Merge anywhere
Draw into an existing road or bridge and it becomes part of the network. No predefined junctions required.
Traffic fights back
Push too many cars through a bad merge and queues form. Vehicles slow down and can stop entirely.
Spend construction
Efficient networks score better. Build beyond your material target if you need to, but every extra unit costs points.
Five maps
Small roads. Increasingly bad ideas.
Each map adds more traffic and fewer obvious answers.

ONE WAY
A tiny traffic sandbox
Easy to draw. Hard to engineer.
Highway Doodles is a browser-based traffic puzzle game about planning efficient one-way road networks. Connect coloured traffic sources to their destinations, decide where lanes should merge, and keep congestion under control.
Bridges let you separate crossing traffic, four-lane roads increase capacity, and construction usage rewards compact solutions. There is no single correct layout: if every car reaches its destination, your strange little highway technically works.
