As you know, I am an experienced road-network and sign (re)builder.
I want to make San Diego map in a 2:5 scale, and I am planning to do Los Angeles later. Maybe this thread best describes my wish: https://www.promods.net/viewtopic.php?f=42&t=13141
Although the project is at the beginning, I think that it is serious. Why? I am fanatic of roads. I like beautiful roads through canyons with tunnels. My country, Serbia, has many such roads. If we look at highways, I like mountainous highways with many tunnels and bridges, like highway Livorno - Nice, or Thessaloniki - Igoumenitsa.
The next type of highways which I like is wide highways (at least 4+4) with complex interchanges. I enjoy looking at the street view or Google Earth. Naturally, I want to drive across them. Los Angeles is maybe the best choice. I started with San Diego because it isn't too far, I-5 has at least 4+4 lanes all way between cities (also I-15), the city is much smaller, and it has enough wide highways and complex interchanges.
I said that the project is serious. As the number of lanes is essential for the full experience, I must make many prefabs and streets.
I know that I want too much. Considering all written above, my focus is on the road network, and I would like to do a good landscape. Then details, including precise signage, must be omitted, but maybe not if I will get help.
So, the goal of this map isn't high quality, but very realistic road network, which lacks in both ATS and ETS.
HELP WANTED:
MAPPERS
PEOPLE WHO WILL ADD DETAILS: unnecessary signs, buildings, fences...
SUGGESTIONS:
I need suggestions for companies in south-western San Diego (between Mexico, I-5, I-8, CA 15, and I-805. For all suggestions, please tell which in-game company I can place and exact places. I need too much time to make crossroads, so I want to waste minimal time on placing companies. I also need suggestions for truck dealers, services, agencies, and gas stations.

This is still only a road map with terrain (and of course, all gameplay objects) — no details, including navigation signs.
