What are the meanings of "water" and "bridge" in architectural geomantic omen?

There are two kinds of water: one is natural water, including rivers and lakes, reservoirs, ponds, wells, rice fields, water storage towers and so on. The other is the road. Because people come and go on the road, it seems to be flowing, so in Feng Shui, the road is also regarded as water. In geomantic omen, water represents wealth. The bridge is in geomantic omen, connecting the two banks of the river and connecting Yin and Yang, so there are legends of haunted bridges in many places.
