Tunnels can be upsized by excavating the existing tunnel to make it larger, or by constructing a new, larger tunnel adjacent to the existing one. This can be done to accommodate larger vehicles, increased traffic, or to improve ventilation and safety. Downsizing tunnels can be achieved by filling in a portion of the tunnel or by constructing a smaller tunnel within the existing space. This may be done to reduce maintenance costs, decrease traffic capacity, or repurpose the tunnel for a different use. Both upsizing and downsizing tunnels require careful planning and engineering to ensure the structural integrity and safety of the tunnel. **

One way to downsize or give up a collection is to carefully assess the items in the collection and determine which ones are the most meaningful or valuable to keep. Then, consider selling, donating, or gifting the remaining items to others who may appreciate them. It can also be helpful to set specific goals and timelines for downsizing the collection, and to seek support from friends or family members if needed. Finally, it's important to remember that letting go of a collection can be a gradual process, and it's okay to take your time and make thoughtful decisions. **
