How to upgrade roads in Cities Skylines 2

Elevating roads is a great way to optimize your city's road network and improve traffic flow. There are two main methods for elevating roads in Cities Skylines 2.

The first method involves adjusting the Elevation parameter. When placing a road, you can adjust its elevation to create ramps and overpasses. This allows you to build roads at different heights, reducing congestion and improving traffic flow.

The second method involves using the Page Up and Page Down keys. By pressing Page Up, you can elevate a road segment, and by pressing Page Down, you can lower it. This method is particularly useful for creating flyovers above existing roads, minimizing traffic issues and improving overall traffic flow.

When elevating roads, it's important to consider the impact on existing city services. Larger roads may destroy buildings next to smaller ones, so carefully plan and strategize to minimize disruptions to important city services.

Highways between districts offer an effective solution for improving traffic conditions in your city. By connecting different districts with highways, you can divert traffic away from congested areas and distribute it more evenly throughout your city.

When planning highways between districts, it's important to consider the potential impact on existing city services. Larger roads may require demolishing buildings next to smaller ones, which can disrupt important services like healthcare or education. Before constructing highways, carefully analyze the potential consequences and plan accordingly to minimize disruptions to your city's functionality.
