The necessary assumptions in any bridge building project include:
- The existence of the other side - There is no point in building a bridge to nowhere. The other side exists and has a right to exist.
- Solidity of both sides - The base or basis of a bridge must be accepted at both ends.
- Existence of a gap (river, canyon, etc.) - If there is only one piece of ground, there is no need for a bridge.
- The gap is not too wide to bridge - No one tries to build a bridge across an ocean.
- The gap is not too deep to bridge - Although deep gaps may exist - and they are very real and not mere illusions - still a bridge can be built.
- The value of a bridge - They are mutually helpful and beneficial. Bridges are costly but worth it.
