The idea for establishing a road along the pass originated with Father Juan Villaverde, a Spanish Dominican missionary priest who worked in Nueva Vizcaya and Ifugao during the late 19th century.[2] The Japanese strategy during the Battle of Luzon was to fight a delaying retreat from Baguio to Bayombong, and then to a final defensive position in Kiangan, Ifugao.A similar defensive battle was fought at Salacsac Pass, along the Villa Verde Trail joining San Nicolas, Pangasinan and Santa Fe.The earthquake displaced two million cubic meters of debris[8] and loosed the area's soil, resulting in more landslides and road closures during heavy rains.[9] Foreign Affairs Secretary Enrique Manalo announced on March 26, 2024 that the Department of Public Works and Highways obtained a JPY100 (P37 billion) loan from the Japan International Cooperation Agency (JICA) for the 23-kilometer four-lane Dalton Pass East Alignment Road Project.[5] The shrine is at the highest point at the "Dalton Pass Viewpoint with Shed" provincial project, which offers long vistas of the mountains and forests.
