The bridge collapsed and flipped over yesterday as people were crossing it in a rural area popular with holidaymakers near the town of Villavicencio.
"According to the information we have, 11 people were killed" including various minors, the head of the UNGRD state disaster management agency Carlos Ivan Marquez told AFP.
Local government official Hilton Gutierrez told the Blu Radio station that one of those killed was an 18-month-old child whose mother was carrying him across the bridge.
