Site details

Redbird Reef is Delaware's best-known artificial reef, 16.5 nautical miles off the coast, built from more than 700 retired New York City 'Redbird' subway cars plus 86 military vehicles, eight tugboats and barges and thousands of tons of ballasted material. The structures sit in roughly 80-110 ft of water and are completely encrusted with cold-water corals, frilled anemones and mussels, with sea bass, tautog and flounder swimming through the car windows. The Chesapeake Cruiser record marks one of the reefed workboats on the site.
