In 2025, Miami Beach launched one of the most ambitious underwater art and conservation projects in the world. According to a report by the Miami Herald, the city sank 22 concrete cars 20 feet beneath the ocean surface, creating a surreal traffic jam designed to support 2,200 corals and marine life. The installation, part of the REEFLINE project, was conceived as a unique blend of art, tourism and climate resilience. The sculptures by individual artists were intended to draw snorkelers, provide habitat for fish, host coral restoration efforts and help protect the city’s beachfront from storm surge.
