Guanajuato Underground Roadways, Mexico

Juarez Street is one of the few through streets on the surface. It is filled with various stores and restaurants and has a constant flow of both people and traffic.

The other through streets of town are either partially or fully underground, following the old drainage ditches and tunnels dug during colonial times. Originally they were used for flood control, but modern dams have controlled flooding and left them dry, so they have been turned into thoroughfares in a city with little surface area.

The most important of these roads is Miguel Hidalgo or Belaunzarán, which carried the runoff from the river that used to divide the city in two. Guanajuato’s version of the La Llorona story has the woman wandering the tunnels of the city, some of which had rivers or streams running through them.
