Ojuela

Ojuela was a small mining settlement located 5 kilometres (3.1 mi) northwest of the nearest town, Mapimí.

With the advent of the railroad, all the extracted ore were transported away from the mine by train and processed in the nearby town of Mapimí.

The town was located at the top of a mountain in close proximity to the mine's main access.

The town developed rapidly from a small settlement to a village with all the urban services of that age.

At the time of construction in 1898, the Puente de Ojuela was the third-longest suspension bridge in the world.

by the Peñoles Company; the original was scrapped and only the main arches are now displayed at the Torreón Exposition Center.
