Roads are what characters travel on to go between locations. The quality of the road will affect what kind of vehicles can travel on it, and at what speed you will be travelling. The length of the road will also affect how long you will be travelling.
Road length and direction
Roads on newer islands have lengths equal to the straight-line distance between endpoints. Roads on older islands can be longer or shorter than the straight-line distance. Roads are always straight - they go in the same direction at every point - but this direction is not necessarily consistent with the direction on the visual map (the directions were generated automatically, but the script used to do this had errors).
Improving the roads can be time consuming. Some resources can be hard to find. For some projects, the required resources can be high. The length of the road and the type of the improvement will dictate how much materials it will take to improve the roads. A shovel or bronze shovel is needed to work on road improvement projects. A wheelbarrow or improved wheelbarrow can be used to speed up road improvement projects.
If an improvement project is started at one end of the road, the town at the other end will not get the option to improve that road. They will not see your improvement project either. All resources must be added (and all the work done) at one end. Road improvement projects cannot be canceled, even if no resources have been used on them.
Types of roads
Paths are the most primitive types of roads. All roads in Cantr are created as paths, and any improvement on them must be done by the characters of the game. Paths have a vehicle speed factor of 80.
Upgrading a path to a sand road requires sand.
All land vehicles can travel on sand roads. Sand roads have a vehicle speed factor of 100.
All land vehicles can travel on paved roads. Paved roads have a vehicle speed factor of 135.
Highways have a vehicle speed factor of 200.
Expressways have a vehicle speed factor of 280.
An expressway cannot be improved any further.
