The Negros Occidental Eco-Tourism Highway, officially known as the BacolodâÂÂSan Carlos Road and BacolodâÂÂMurciaâÂÂDon Salvador BenedictoâÂÂSan Carlos Road, is an scenic highway that connects the city of Bacolod to the city of San Carlos in Negros Occidental, Philippines. It cuts through the north-central Negros Island and traverses the Northern Negros Natural Park, north of Mount Kanlaon. Its western segment in Bacolod also known as Alijis Road (Romeo G. Guanzon Avenue) has a two-way bicycle lane.
The entire highway is designated as National Route 69 (N69) of the Philippine highway network.
The road starts in an intersection with the Bacolod South Road beside the BacolodâÂÂSilay Airport. The road has a stretch in Bacolod which is named the Bacolod-San Carlos segment. Shortly after the highway starts, the road intersects with the Bacolod Circumferential Road. The highway trails southeast before intersecting with the Bacolod Economic Highway, ending shortly after.
The road enters Murcia, Negros Occidental at the Department of Public Works and Highways 3rd district in the province with a stretch. The road tracks more southeast, intersecting with the Murcia-Cansilayan-Damsite-Abuanan-Bago City Road. The road then trails east, before going north.
The highway originated from an old road connecting Bacolod to the foot of Mount Kanlaon in Murcia that is also historically part of Highway 336. It was later extended to San Carlos sometime after World War II.
