Assetto Corsa was built for circuits. The reason people still play it more than ten years later is the roads the community has added. A motorway at night with traffic, a V10 and nowhere to be is something no other sim does as well.
This page is about highways and fast roads. If you want the scenic open maps, those are in my best Assetto Corsa free roam maps. I checked every length, price and author below on 5 October 2026.
The short list
| Map | Road type | Length | Price | Best for |
|---|---|---|---|---|
| Shutoko Revival Project | Tokyo city expressways | Around 160 km | Free | Traffic, night cruises, online servers |
| Hamburg A7 by 4R | German Autobahn, 2 to 6 lanes | Not published | Paid, Patreon | Top speed runs |
| Black Cat County | Desert highway loop | 6.5 to 11.2 km | In the game | A first try with no mods |
| LA Canyons | Mountain highway | 42 km loop | Free, paid extras | Fast flowing corners |
| Pacific Coast | Coast road | 23 km | Free | A relaxed drive |
| Union Island | Island roads, 1:1 scale | 33.5 km | Free | Mixed driving and scenery |
| High Force | British B road | Just over 30 km | Free | Narrow, technical driving |
What you need first
Almost every map on this page needs two free tools:
- Content Manager. The launcher that replaces the original one. You install a map by dragging the zip file onto it. Here is how to install Content Manager.
- Custom Shaders Patch (CSP). The patch that adds night lighting, rain and the traffic features the big maps rely on. You install it from inside Content Manager.
New to mods? Start with how to download mods in Assetto Corsa. And know that these maps are heavy. They are far bigger than a circuit, so the download is large and the first load takes a while.
1. Shutoko Revival Project
This is the one. A recreation of the Shuto Expressway, the network of elevated motorways that runs through and around Tokyo. Around 160 km of road: the tight C1 loop in the centre, the long straights of the Bayshore Route, the tunnels, the junctions and the parking areas where people meet.
It is free. You download it from the project's own site, shutokorevivalproject.com, not from the usual mod sites. The last version number I see quoted is 0.9.2, so check the site for the current build before you install.
Why it is the best highway map:
- The size. You can drive for an hour and not see the same corner twice.
- The servers. Most of the big online traffic and cruise servers run this map. You join, there are AI cars in every lane and real players around you.
- Two kinds of driving. The C1 is tight and technical, more like a street circuit. The Bayshore Route is where you find out what top speed your car really has.
One piece of advice from a racing driver. The C1 has concrete walls and no margin, like Monaco or Macau. Learn it at seven tenths. The people who are fast there are smooth, not brave.
More detail in my Shutoko Revival Project guide.
2. Hamburg A7 by 4R
If what you want is a real motorway with no speed limit, this is it. The modder 4R has built the A7 through Hamburg at 1:1 scale: 2 to 6 lanes from Heimfeld in the south to Quickborn in the north, through the harbour, the city and the tunnels.
It is part of a bigger plan. 4R also has maps for Denmark, Sweden and Stockholm, with more than 23 km of Swedish motorway in the Stockholm map alone, and the idea is that they connect into one long route from Hamburg to Stockholm.
The catch: it is paid. The maps are on the 4R Patreon page. I would try Shutoko first, because it is free, and come here when you want wide lanes and long straights.
3. Black Cat County
Most people forget this one, and it is already on your PC. Black Cat County is an official Kunos track, added to the game with version 1.5. It is a fictional desert highway in the American style, and Kunos made it for exactly this: driving a road car without learning braking points.
Three layouts:
| Layout | Length |
|---|---|
| Black Cat County | 6.48 km |
| Short | 6.54 km |
| Long | 11.24 km |
It is small next to the mods. But it works on console too, it needs nothing installed and the AI can drive it. If you are not sure highway driving is for you, do ten minutes here first.
4. LA Canyons
LA Canyons, by Phoenix77, is based on the real roads in the San Gabriel mountains above Los Angeles. The main loop is 42 km, 47 km with the side roads. It is a mountain highway and not a motorway: two lanes, fast third and fourth gear corners, big drops.
The main version is free and comes with six layouts, including a free roam one. The traffic pack with two way traffic is a paid VIP extra from the author.
This is my pick if you want to actually drive. A road like this teaches you more than a straight motorway: you have to look far ahead, and every corner is a little different from the one before.
5. Pacific Coast
Also by Phoenix77, and free. 23 km of the Californian coast road, with the ocean on one side and the hills on the other. It is shorter and easier than LA Canyons, with wider corners and better visibility.
6. Union Island
Union Island is a real island in St. Vincent and the Grenadines, in the Caribbean. The map by Ben O'Bro recreates it at 1:1 scale, with 33.5 km of road. It needs CSP to run.
There is no motorway here. What you get is a full small island: a town, coast roads and hills. It is the best map on this list for a slow car and a long session.
7. High Force
High Force is a British country road in County Durham, in the north of England, named after the waterfall next to it. Just over 30 km, narrow, bumpy, with stone walls close to the edge. It supports rain and night, and it works online.
It is the opposite of a motorway, and that is why it is on the list. If the Autobahn bores you after twenty minutes, this will not.
How to get traffic
A highway without traffic gets empty fast. There are three ways to add it.
| Way | Cost | How it works |
|---|---|---|
| Join an online traffic server | Free | Open the Online tab in Content Manager, search for the map name and join. The server runs the AI traffic, you only need the map and the cars |
| A traffic layout with AI cars | Free or paid | Some maps have layouts made for traffic. You start a normal session against slow AI cars and they act as traffic |
| A traffic tool for CSP | Paid | Tools such as 2Real add traffic to your offline sessions on supported maps |
I would start with the first one. It costs nothing, and it is how most people drive Shutoko anyway. Each server lists the car pack it needs, so install that first.
Which map should you pick?
- You want traffic and other people: Shutoko Revival Project.
- You want maximum speed: Hamburg A7, or the Bayshore Route on Shutoko.
- You have no mods and want to try it now: Black Cat County.
- You want corners: LA Canyons, then High Force.
- You want to relax: Pacific Coast or Union Island.
For the car, anything works, but a road car makes more sense here than a GT3. The drift car mods and the drift track mods are the next stop if you get into the street side of the game.

Only Black Cat County. Mods are for the PC version of the game.
Do I need Custom Shaders Patch for these maps?
For most of them, yes. Shutoko Revival Project and Union Island need it, and the lighting and rain on the other maps depend on it.
