STREET IN GUANAJUATO, MEXICO 



The Guanajuato River formerly ran through the center of the city, a swirling, churning, 

 much-bridged mountain stream. But every heavy rainfall in the mountains brought a flood 

 to the city, sometimes with the most disastrous consequences. Finally, a cloud-burst in 1905 

 caused so much damage that a tunnel was constructed to divert the overflow. The project 

 cost $350,000.
