Lighthouse Beam Sweeps Tbilisi Viaduct at Night

A powerful beam of white light cuts horizontally across the underside of a massive concrete viaduct, illuminating the rough texture of the structural supports against the pitch-black void of the Tbilisi night. The lighthouse sweep reveals the sheer scale of the bridge span rising above, where smooth gray surfaces meet the deep shadows of the valley below. Thick fog rests on the ground, appearing as a dense, white carpet that swallows the river far beneath the structure. The clear midsummer sky remains invisible above the bridge deck, focusing all attention on the engineered geometry and the sharp, artificial glow that defines the scene. The light edge creates a stark line against the dark concrete pillars.
