The Highway is the largest road available in Cities XL as of date.
The highway is unlocked at a late time of the development of a city (500 000 pop), and can handle the most traffic out of all the roads.
It has a capacity of 320 cars per minute and costs 540c per 40 metres.
The highway is an exclusive transport corridor, and as such has the following special rules:
- You can't make normal intersections with a highway, because other roads can't cross with it on the same level. You need to either use one of the set pieces to connect it to the rest of the road network, or you need to build bridges/tunnels to go over/under it.
- Highways don't provide your buildings with road access! That means that if you build something adjacent to a highway, the building will have the 'Not connected to the City Hall' icon and won't function. So, you must provide an alternative, normal road access to buildings close to a highway.
- You can only draw highways with the curved tool for some reason (unless you have a mod installed).
Here are the connector pieces that allow connection of highways with the rest of the road network:
|Connector piece||Cost||Maintenance fee||Connects|
|Simple Interchange||2000 c||420 c/mo||Expressway to Highway, direct conversion|
|Large T Interchange||1800 c||400 c/mo||Large Avenue to Highway, T-shaped connection|
|Very Large T Interchange||1800 c||400 c/mo||Highway to Highway, T-shaped connection|
|Cloverleaf||2700 c||600 c/mo||Highway to Highway, cross connection|
