In New Orleans' Lower Ninth Ward, a new infrastructure project has reopened old wounds.
For more than 50 years, the Army Corps of Engineers has tried to expand the Inner Harbor Navigational Canal. The shipping canal connects the Mississippi River to Lake Pontchartrain. Now, officials want to dig it up and build a new lock to let more tugboats and barges through.
But the people of Lower Ninth are not having it. The conflict is emblematic of a long history of mistrust.
