You have a point. I always use that highway to enter and leave the city, its impossible to enter and leave the city using the shortest way. I think that you have a good idea blocking roads

Like Duisburg, Calais needs a rework. Repair stop far away of the garage and the exit/entrace of the city and companies. I think it would be nice to have more than one road to leave the city and a gas station like Duisburg to ease the traffic on the first gas station in the Calais/Duisburg road. I don't know how to edit photos, so I did it with paint with the actual city would be amazing to have a secondary road like this.

I think this road needs two modifications to avoid problems. Gas stations needs to be optimized, there's always a lot of traffic. The train closes the way every 30 seconds, making a huuuge problem. Maybe modifying the time for the train to cross will reduce the traffic, and several modifications on those two gas stations will reduce the traffic like... A lot! This is the most crowded road in the game, a lot of people love this road (me included) but is time to modify it to optimize the actual traffic.

Looks like Minecraft chat
