[3] The paved and graded road system continues past that intersection and has been extended year by year in a westward direction to the crest of the Sierra Madre Occidental and down the western slope of the Sierras, following the drainage of the Topia River, past Canelas, Durango and then on to the end of construction in a dead end about 24 km.

This terminus of the graded and paved road is only 32 km (20 mi) by direct line from Tamazula de Victoria, Durango.

It is unknown whether there will be further road construction beyond La Angostura to Tamazula de Victoria in the coming years though that would be feasible from an engineering standpoint.

It terminates at the remote village of La Angostura, beyond Canelas, Durango on the west side of the Sierra Madre Occidental, in the drainage of the Topia River.

This terminus of the graded and paved road is only 32 km (20 mi) by direct line from Tamazula de Victoria, Durango.

36 does NOT extend to Topia, and in fact goes far beyond this intersection to the crest of the Sierra Madre Occidental and then goes down the west side, to an unfinished dead end some 24 km (15 mi) beyond Canelas, Durango, as noted in the next section.

It runs to the remote village of La Angostura, beyond Canelas, Durango on the west side of the Sierra Madre Occidental, in the drainage of the Topia River.

Since this road ends at the small community of Angostura, Durango, which happens to be the home of Ines Coronel Barreras, a cattle rancher and Sinaloa drug lord, who is the father of Emma Coronel Aispuro, the Mexican beauty queen and wife of the internationally notorious drug lord Joaquin "El Chapo" Guzman, it is uncertain whether there is any plan to construct the road down to Tamazula de Victoria, Durango, which lies only 32 km (20 mi) to the west.

From Canada del Macho these roads pass south through the village of Santa Efigenia (24.993033° -106.503020°), then 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, Durango (24.811031 -106.738821) and southwest to Bayosa, Durango (24.771525 -106.766086) and southwest through Mezcaltitan, Sinaloa (24.681667 -106.814444) until intersection with a paved road (24.624593 -106.827472) running between Culliacan and Cosala, Sinaloa via Presa El Comodero.

Though not as notorious as the unpaved area of Mexican Federal Highway 24, the travel on this route off the west side of the Sierras should be considered to be one in which unpredictable dangers could be encountered.
