History

Route description

Tagbilaran to Trinidad

The route starts as Tagbilaran North Road, or the Carlos P. Garcia North Avenue from the Old Provincial Capitol of Bohol, now the Bohol National Museum. It passes through the city proper northwards to the state university campus, towards the towns of Cortes, Maribojoc and Loon, where motorists can access Sandingan Island and its barangays thru a spur road. The road continues through the towns of Calape, Tubigon, Clarin, and Inabanga, then heads eastward inland and curves back northward into Buenavista and Getafe and Talibon, where three ports provide access to islands to the north and west of Bohol. The road then goes southward inland towards Trinidad where the segment ends in a three-way intersection with Loay Interior Road, also called the Loay–Trinidad Road, and the Tagbilaran East Road.^[4]

Trinidad to Tagbilaran

The route continues as Tagbilaran East Road after the junction and meets the road towards another port at the town of Bien Unido, then goes east to Ubay, where transport services to Leyte and nearby islands are located. The road heads inland southward to the towns of Alicia, and to Candijay, where a circumferential road going to the southeastern tip of the island is located, to the towns of Guindulman and Anda. The road continues south to the town proper of Guindulman and heads southwest while running beside the coast to Duero and Jagna, where transport services to Camiguin and the island of Mindanao are located. The road continues running along the coast to the towns of Garcia Hernandez, Valencia, Dimiao, and Loay, where the highway running through the island towards Trinidad is located. It continues westward to Alburquerque, Baclayon, and back towards Tagbilaran, where motorists can access the towns of Panglao and Dauis southwest of the city. After reaching Tagbilaran again it ends at the kilometer 0 of the island.^[4]

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]
