Three adult males are observed inside a well-lit, concrete-lined tunnel in Antony, France. All individuals wear high-visibility orange work jackets with reflective stripes and hard hats. The man on the far left wears a white hard hat with an attached headlamp, a black utility pouch, and has a lit cigarette in his mouth while facing right. The central figure is viewed from behind, wearing a striped hard hat and an orange jacket over a dark blue garment. The man on the far right wears a black hard hat with a headlamp and an orange vest over a black jacket, looking towards the left. All three are seated on wooden planks forming a temporary platform. The tunnel structure comprises modular concrete segments. Overhead, multiple metallic cable trays and conduits are affixed to the ceiling. A continuous strip of white LED lighting runs along the upper right wall of the tunnel, providing illumination. A metal grate walkway with railings is present to the right of the seated individuals. A fourth person, also in high-visibility clothing, is partially visible further down the tunnel.
