The quote "All that way, and he never crossed the bridge" from David Mitchell's novel "The Bone Clocks" reflects the idea of unfulfilled journeys and missed opportunities. It suggests that despite the time and effort taken to reach a destination, sometimes individuals fail to take the final step that would lead to significant change or enlightenment. This can resonate with readers who have experienced similar feelings of hesitation or regret.

In the context of the book, this notion may symbolize the characters' struggles with their choices and the paths they take in life. It emphasizes the importance of not just being physically present in a situation but also taking meaningful action to achieve personal growth or deeper understanding. The bridge becomes a metaphor for the crucial moments in life that define one's direction and purpose.
