Lyric discussion by Kyomara 

Cover art for Anchorage lyrics by Michelle Shocked

Glenman, there's no actual "burning bridge." She's singing about getting back in touch with a relationship she had been neglecting. It's the old metaphor about "burning your bridges," cutting off connections to your past. Her connection to this friend was in danger of disappearing.

@Kyomara You said it better than me...but mainly, she needed a rhyme for anchorage.
