A new light rail project connecting parts of South Central Los Angeles, from Crenshaw to LAX, broke ground today. At a ceremony at the Expo/Crenshaw light rail station, US Transportation Secretary Anthony Foxx said the light rail will spur local economic development in the area. But, local activists held a demonstration against the project as is. They contend that the above-ground stops will devastate L.A.'s "last black business corridor." Pacifica's Dan Fritz has the story.
