Temporary string lights and work floods — harsh white pools

Fresh survey marks in fluorescent pink and orange spray paint

Distant jackhammer, closer sounds of dripping from fresh-cut rock

Tunnel boring machine components, rail segments stacked, fresh concrete

Concrete dust, diesel, the sharp smell of freshly broken stone
DEPTH
Beyond the last station, heading nowhere yet
