    Incidents
    • This highway had many bridges and sections of Tagbilaran North Road and Tagbilaran East Road damaged during the 2013 Bohol earthquake.[5] A few bridges were reconstructed with the Mabey Compact 200.[6]
    • On April 27, 2022, the old bridge over the Loboc River in Loay collapsed, killing 4 people and injuring 15. The bridge was damaged during the 2013 earthquake and still being used while a new replacement bridge was under construction next to it. One possible cause was the stationary traffic on the bridge that exceeded its capacity.[7]
