Road Interchanges

12/07/25

“How can roads cross each other while changing height?”

Road junctions allow people to cross from one road to another. But sometimes it’s not wise to allow for crossings at the same height, such as when people have to load onto freeways. One way to do this is to build a Road Interchange where crossings happen at grade separation. Separating roads at different heights allows vehicles to cross roads without stopping.
