Taking the significance of 'Chinese Dragon' as a symbol of strength and good luck, and also echoing the celebration of the annual Dragon Boat event, the metaphor of Dragon has been used in the concept of design.

The metaphor of Spine would, in fact, have two folds of meaning. First, since Tai O has been one of the most prosperous and oldest village in Hong Kong, it could be said as being the 'spine' of the development of Hong Kong. Second, as one of the foremost projects in the revitalization process of Tai O, this new bridge is considered as the 'spine' for the future rebirth of Tai O.
