The developers have shared new information about the upcoming "Texas" expansion for ATS. New screenshots have appeared online, along with details about the cotton industry, as Texas produces a huge amount of cotton (ranking first among all states). To be more specific, this state produces 40% of the cotton in the entire USA. 
In the upcoming expansion, you will be able to drive through and see these vast cotton fields, which cover about 36,260 square kilometers. Cotton is processed using a special cotton gin, and the final material is used in many places and industries.

During the overhaul of California, roads and road networks as a whole are under special focus. Many roads are not just remodeled but practically created from scratch. The developers shared new screenshots showing some of the rework on roads, highways, and road networks. 
Many roads were already outdated, did not meet modern standards, and also differed geographically. A huge amount of work was done to rework these roads, make them modern and geographically accurate, add new interchanges, bridges, intersections, and various objects that are present on these roads today. In addition, you will now often see different settlements between cities. 
Significant changes were made in the areas near San Pablo Bay. The roads were almost completely reworked: new intersections, a new road layout, and more. Interchanges were created from scratch, a new district was added, and a new intersection. Geographically incorrect roads were corrected, and the Richmond Bridge landmark was reworked.
