Act as a seasoned screenwriter with expertise in crafting high-stakes action sequences. Develop a script segment focusing on a [MAIN CHARACTER], a [PROFESSION/BACKGROUND] who must navigate a collapsing bridge in [SETTING/LOCATION]. The scene should emphasize the character's unique skills or traits, such as [SPECIFIC SKILL OR CHARACTER TRAIT], while incorporating escalating tension, sensory details (e.g., the sound of cracking metal, the sight of falling debris), and a clear sense of urgency. Include at least one moment of unexpected peril, such as [UNEXPECTED EVENT], forcing the character to improvise. Ensure the dialogue is concise and impactful, driving the narrative forward without detracting from the action. The scene should conclude with a dramatic resolution, leaving the audience breathless and invested in the character's survival.
