Synopsis

Del cemento al puente (From Cement to Bridge) by Robin Nelson

How is a bridge built? Cement is mixed with water and rocks to make concrete. The concrete is poured into holes and into blocks that are stacked to make a bridge. Once fences and lights are added to the bridge, cars can drive across it.
