Photos of the Holland Tunnel "Sandhogs": Faces of the Men Who Dug Under the Hudson

Yes—extensive photographic archives exist of the "sandhogs" (compressed-air tunnel workers) who built the Holland Tunnel (1920–1927), the world's first mechanically ventilated vehicular tunnel.

What the Photos Show

• Workers in "mucking" gear – Hard hats, rubber coats, hip boots, respirators (for silica dust).
• Shield tunneling – Men inside the Greathead shield, excavating by hand/pneumatic spade.
• Compression/decompression – "Hogs" entering/exiting air locks; "bends" treatment in medical lock.
• Segment erection – Bolting cast-iron tunnel rings; grouting behind lining.
• Ventilation towers – Construction of the 4 massive shafts (still landmarks).

Human Cost

14 sandhogs died (caissons disease, blowouts, accidents). Photos capture both heroic camaraderie and industrial brutality—men breathing pressurized air, ears popping, bones aching, building a passage that changed a region forever.
