The 2nd Street Tunnel is a widely filmed and photographed tunnel on 2nd Street under Bunker Hill in Downtown Los Angeles, California. It has been described as "the most recognizable city landmark most Americans have never heard of". It is 1,500 feet long, and lined with glossy white-glazed tiles that bathe the tunnel in a unique and desirable light – described as "one big light box" – which creates unusual textures.
