Noontime light, long criticized for the boring shadows it grants photographers, comes into its own sometimes.
The newer tunnels were fitted with these fluorescent lights, although some skylights (block glass embedded in skywalks) let in some natural light during the day.

“See anything?” “No, just more of it.” “How much to go?” “Oh god–we’ve only seen about 10%.” “Guess we should keep moving then…”
The nitrating house was a chemically dangerous place, so it had thick metal and concrete shield for every station right next to an emergency shower.
The first 800 or so feet of the tunnel is finished with reinforced concrete. The test is raw stone. This is the spot where it switches. Side note: nailing this shot on film is one of my proudest light-painted moments.
