Havana Flood Barrier Wall Twilight

Steel-blue ambient light washes over a massive concrete flood barrier wall stretching across a windy overpass interchange in Havana. The surface glistens with a thick layer of sea salt and driving rain, turning the gray texture into a slick, dark mirror. Indigo twilight settles deep in the sky above the interchange, against the faint heat shimmer rising from sun-struck surfaces below. The wide panoramic view shows the sheer scale of the infrastructure, emphasizing its practical grandeur against the cooling evening air. Water droplets rest on the rough edges, while the wet concrete reflects the fading sky. A final streak of rain slides down the vertical face, leaving a darker trail against the pale gray stone.
