Federal Highway 36 (Carretera Federal 36) is a Federal Highway of Mexico. The highway, located entirely within the state of Durango, begins in the city of Topia and runs eastward to the town of Los Herrera.
Mexican Federal Highway 36 has an eastern terminus that starts from a "T" intersection with Mexican Federal Highway 23, as that highway extends between Santiago Papasquiaro Municipality and Tepehuanes Municipality. The intersection of Highway 36 with Highway 23 is 10 km north of Santiago Papasquiero and 42 km south of Tepehuanes. This intersection is 5 km. south of Las Herreras, Durango so this town may is referred to as the eastern terminus of the highway.
From the intersection with Highway 23, Mexican Federal Highway 36 climbs up into the chain of coastal mountains to the west. The paved road extends for about 106 km (66 mi) until the pavement ends on the crest of the coast range (25.092121°, -106.487220°).
At a point about 96 km (60 mi) from Santiago de Papasquiaro a road leads off of Highway 36 and extends 28 km (17 mi) to Topia, Durango. This intersection is located at (Long. 25.142146°, Lat. -106.452445°). The road from Highway 36 to Topia is a narrow dirt road. Although Topia is sometimes listed as the western terminus of Federal Highway 36, the pavement and improved construction for Highway 36 leads on past this intersection, for an additional 10 km (6.2 mi).
Federal Highway 36 has been extended periodically in the last 10 years. It is projected to be eventually completed down to the Pacific Coast Area in Sinaloa at Tamazula.
In the last 4 km (2.5 mi) of paved road, starting at a small community of La Cañada del Macho (Lat. 25.118271°, Long. -106.472833°), a network of unpaved but graded roads leads down off the west side of the summit ridge to Canales, Durango, reaching there after about 20 to 25 km (12 to 15 miles), descending in steep pitches from the ridge at about 2550 m. to about 1350 m. at Canales.
Roads are being constructed directly west from Canales. However this network is not yet completed and cannot be presently relied upon to provide access off the western side of the mountain range to the paved roads along the Pacific Coast. This road construction, if completed may eventually allow access to the roads on the Pacific Coast from Canales.
At the end of the pavement at or near Canada del Macho, another network of unpaved and unimproved roads continues down off the western slope of the Sierra Madre Occidental finally reaching highways on the Pacific coast. From Canada del Macho these roads pass south through the village of Santa Efigenia (24.993033° -106.503020°), the south to a point (24.948837° -106.516770°), and then west to Llano Blanco (24.953691° -106.601568°), south through El Bajio (24.934765° -106.625653°) and La Huerta (24.861016° -106.610385°), to a fork (24.822571° -106.632597°) where the road turns west and descends down the mountain to Chacala, and southwest to Bayosa, and southwest through Mezcaltitan until intersection with a paved road running between Culliacan and Cosala, via Presa El Comodero.
