I was a teenager in junior high when I first heard of the 105 freeway construction. My friends were being asked to move from their homes. Then I didn't hear anything else. Years later, I watched in awe as the landscape changed around us. As we went about our daily lives, street corners moved and moved back; underpasses appeared where solid ground once was; ramps and overpasses grew and snaked their way around Los Angeles, sometimes nervously close to existing structures.
