Cities: Skylines 2 - Extended Road Upgrades

[!IMPORTANT]

We're in the early stages of C:S2 modding and the tooling is not ready yet so please take this mod as it is and accept any issue.

This mod enables both quays, retaining walls and elevated upgrade options in the Network Upgrade tool.

[!WARNING]

This mod might mess up your save game. If this happens and some of your roads are acting weird you can bulldoze and recreate them to fix any issue.

CHANGELOG

Description

This mod enables some additional upgrade modes for your roads, giving you full control on the type of roads you can build without needing to precisely terraform beforehand.

These upgrades are available in the in-game upgrade mode for roads and can be used exactly like any other upgrade mode (e.g. Grass or Wide Sidewalk).

The mod currentyl supports the following modes:

  • Quay
  • Retaining Wall
  • Elevated
  • Tunnel

These upgrades can be applied to:

  • Roads
  • Pedestrian Paths
  • Public Transport Roads
  • Train Tracks
  • Tram Tracks
  • Subway Tracks

Setup

Each release will contain 4 different download zips:

  • ExtendedRoadUpgrades_-BepInEx5.zip
  • ExtendedRoadUpgrades_-BepInEx5_Debug.zip
  • ExtendedRoadUpgrades_-BepInEx6.zip
  • ExtendedRoadUpgrades_-BepInEx6_Debug.zip

[!TIP]

Debug versions can be helpful to have extended logging in case of errors, they're not intended for daily usage

Simply download the release that matches your BepInEx version from the releases page and extract the ZIP file to your BepInEx/plugins folder.

Requirements

  • Cities: Skylines 2
  • BepInEx, either v5 or v6
  • BepInEx 5.4.22
  • BepInEx-Unity.Mono-win-x64-6.0.0-be.674+82077ec

Usage

You will find new icons in the Road Upgrade menu, just after the _Grass_ one.

Select one of them and upgrade your roads as you would with the other available upgrades.

Known Issues

Please see the official issue tracker.

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. Most mods rely on the game's mod loader — the usual route is a community mod manager (such as r2modman): pick this game, install, and it handles the loader and dependencies.
  3. For a manual install, put the mod files into the matching Mod / plugins folder inside the game directory.
  4. Launch the game to confirm it loaded; mods with listed dependencies need those installed as well.

Install locations vary a lot between mods — the bundled readme is the most reliable guide. Code mods go into the Mods folder inside the game directory and must be enabled from the in-game Mods menu.

Dependencies

Install these first, or the mod will not work:
