Kennon Road, also known as Rosario–Baguio Road, is a two lane roadway in Benguet province in the Philippines connecting the mountain city of Baguio in Benguet to the lowland town of Rosario in La Union province. The project begun in 1903 and opened for travel on January 29, 1905. Originally called Benguet Road, it was later renamed in honor of its builder, Col. Lyman Walter Vere Kennon of the U.S. Army Corps of Engineers. It is the second oldest road that leads to Baguio, after Quirino Highway, and the shortest route to Baguio for travelers from Manila and provinces in central and southern Luzon. The entire road forms part of National Route 54 (N54) of the Philippine highway network. Route description Coming from the lowlands, Kennon Road is one of the four major access roads that lead to the highland city of Baguio. The upward climb reveals a picturesque view of the mountains, lush vegetation, and pine trees as one gets closer to the city. Most of the highway's stretch encompasses the municipality of Tuba in the province of Benguet. The small settlements along the road, known as Camps 1 to 8, were originally established for the pioneer builders of the road, but have been occupied since by local residents. The Bued River flows along a rocky canyon from the lofty heights, and following this course the road was cut above the river bed. The highway is a toll road, with the lower tollgate located about from the junction at Rosario near Camp 1. The upper tollgate is about south of Baguio near the Lion's Head and Camp 6, in Tuba. The steepest portion of the road between Camp 6 and Camp 7 in Baguio is commonly known as "Zigzag Road" because of the numerous switchbacks required. The design of the road switchbacks along that section of the road are similar in construction to the agricultural rice terraces found locally in Benguet and the other mountain provinces of the Cordillera Administrative Region. History As the Americans wanted to make Baguio a summer retreat to solidify Manila’s position, they decided to build a sturdy and reliable road to go there. They first tapped Charles W. Mead, who was a civil engineer. But was subsequently replaced by Colonel N.M. Holmes. Two years after in 1903, the project was turned over to the administration of Lyman Kennon. The construction of the road commenced
