Honest questions. In these neighborhoods are lorries permitted to drive certain areas? Are all deliveries by bicycle wagon or similar? How do tradespeople bring tools/equipment. How is building/remodeling handled in areas that have little to no vehicle access and heavy equipment needs to be used?

I ask because I’ve lived my entire life in car-centric Midwest U.S. I have traveled in Europe but have not lived there, and so the day to day logistics are a mystery to me. Please help me cure my ignorance <3
