In one of his last acts as mayor, Ray Nagin dedicated the Roots of Music Cultural Sculpture Garden in Armstrong Park. He had to open it without all of its featured sculptures because some weren’t ready on his schedule, while one piece rested on a plywood platform because its pedestal wasn’t ready yet. Recently, the Congo Square sculpture was added, but in today’s Times-Picayune, Katy Reckdahl reports that the garden is closed because of hasty workmanship. In the month since it opened, the sidewalks have already cracked and become muddy messes that have to be replaced.
