Reapply to jobs I turned down?

A few months ago, I was interviewing with multiple jobs. I accepted one job and turned down others, some after a few interviews, some after initial contact. Fast forward to now, my new job was a terrible fit, and we mutually decided to end it. I see these other jobs I turned down still active on job boards. Should I contact them to see if they are still interested in me? Or did I burn those bridges by turning them down? Anyone with experience, please help. Thank you!
