In the Mexican city of Monterrey, where the over development of newly built suburbs affect peoples daily lives and customs, there is a large bridge spanning Highway 85. On that bridge Alejandro Cartagena pointed his camera down at the morning traffic. He was seeking and peeking into the backs of open trucks, where construction workers often pile together on their way to earn a living. Like commuters everywhere, they sleep, eat, read and talk on their way to work. Often they look up, and maybe they notice someone taking their picture.
