Going to bump this for a good reason...
I have modded Komojo's Pacific Yosemite map rip into the racing simulator Assetto Corsa!
The map is a freeroam map with 32 pits. It has been enhanced to support a day/night cycle. I have smoothed out the road meshes to make them more drivable in a modern racing game (rather than have the cars bounce all over the place trying to drive over the jagged angles); however, if you would like to try racing on the 90s geometry I have created that as a selectable variant as well. The visuals remain unchanged for both versions, the smoothing was done on an invisible mesh that the physics engine uses.
Here are some screenshots and a quick video to show off the map:
Here is the download link for the mod:

PLEASE READ HOW TO INSTALL
Edit: Here is a text guide, along with links to tutorial videos and additional mods for cars that were in TD3 https://pastebin.com/sS5BPV84
This mod was made for Assetto Corsa running Custom Shaders Patch v1.66 using Sol 1.5.4 + 1.6.x. The game should be launched with Content Manager and not the default Assetto Corsa launcher.
Custom Shaders Patch and Sol are 2 additional mods for Assetto Corsa that add many new features to the game. If you do not use them when trying to run this map, many features will be broken and/or missing. There are many guides online on how to install both of these mods, follow them when installing Custom Shaders Patch and Sol. Content Manager is a tool that does exactly what it is named, it managers Assetto Corsa content as well as assists with Custom Shaders Patch + Sol. There are many guides on Content Manager as well that I suggest you follow to set it up.
After you have installed Custom Shaders Patch, Sol, and Content Manager, you can drag the unzipped pacific_yosemite folder into ...\assettocorsa\content\tracks
If you are unable to install this mod, I can try to provide additional help in this forum.
Some minor things of note
You are able to fall straight through the map if you drive far enough off of it. To my knowledge, TD3 had infinite level streaming so the map would repeat. This does not exist in Assetto Corsa. I have surrounded the map with fake non-collidable maps to simulate the effect visually. If you drive on one of these fake maps you will just fall straight through.
Some small things are missing collision (example: road signs). This was done intentionally as these objects were too small that accurate collision on them would have the car get stuck inside the object.

Everyone in this thread for keeping the interest in TD3 alive
This map was a ton of fun to convert and I learned a lot of neat tricks along the way. I hope you enjoy!
