Lethbridge changes constantly, but one force remains relentless: the blistering, unyielding wind.
Over a century ago, those ferocious coulee gales nearly derailed the construction of the Lethbridge Viaduct—the High Level Bridge. To battle wind shear that threatened to topple 320-tonne steam cranes and un-riveted steel, engineers poured massive concrete deadman anchors deep into the hillsides, pinning heavy cableways and guy lines against the gale.
When the last of the 1.4 million rivets was set in 1909, the bridge stood indestructible. The temporary cables were stripped away, but the concrete anchors stayed—silent monoliths half-buried in the sagebrush.
They still rest along the upper coulee banks today: heavy, weathered monuments to the quiet engineering that tamed the Lethbridge wind.
