First of all, Thank you Developers for bringing a new innovative title into the very stale gaming scene.
Played the latest patch and fooled around with the road transport update a fair bit. If I could weigh in on this design choice, its a good addition but it requires some fine-tuning.
Transport Hub: We require the ability to channel resources from one point of the map to the next in order to plan a rapid construction project. I feel the Transport hubs can be utilized with a menu system to control this. Then we can the use the storage hubs paired to the Transport hubs in order to create depots in the logistics network.
Road Construction: Allow the build tool to pull/extend the direction of the road to be built instead of having to build individual blocks.
Underground/Tunnel road network: This could be useful addition @ premium resource allocation and power as a trade off.
