The signature work is Leandro Erlich's 'Concrete Coral', a submerged traffic jam of full-size cars queued across the sand. Status, phased build, verify current deployment before adding to a live map. Conceived 2019 by curator Ximena Caminos as a hybrid of public art, snorkel trail and hurricane-surge breakwater for Miami Beach. Repeatedly delayed by permitting; treat as 'coming soon' rather than confirmed. Anchorage: Nearshore Miami Beach; day access. Hazards: No site-specific hazards noted, brief normally. Plus
