In 2025, Miami sank 22 concrete cars beneath the Atlantic; what looks like an underwater traffic jam is actually a giant artificial reef for 2,200 corals

Beneath the waves off Miami Beach, a striking collection of 22 concrete cars lies submerged, serving as artificial reefs that support coral restoration and marine life. The unconventional sculptures are providing new surfaces for corals and other marine organisms to grow. The innovative project combines art with environmental conservation, while the restored reef is also intended to help protect the coastline by reducing wave energy and erosion.
