A six-kilometer commercial artery carved through the mid-levels of the megacity's western residential stacks, The Phosphene Corridor exists in a state of perpetual artificial noon. Every surface that can hold a light source does — holographic canopies overlap in layers three and four deep, advertisement drones circle in lazy holding patterns, and the storefronts themselves have been rebuilt so many times that their facades are geological strata of signage. What began as a modest entertainment district in the city's second construction phase has metastasized into one of the most densely trafficked consumer zones in the entire corridor, drawing an estimated 400,000 pedestrian movements per day across its elevated walkways and sub-street arcades.
