When I remember how intensely interested I myself became in watching the progress of this wonderful building I often wonder what the feelings must have been of those to whom success or failure meant so much,--the builders themselves. Never shall I forget the tenseness of the closing days of that undertaking,--the grim, silent determination written in the faces of those men! In spite of the Doubting Thomases (of whom, I confess, I was one) the thing was triumphantly, gloriously accomplished.
It was at the cost of two years of the stiffest fighting that Man has ever put up against Nature. The great concrete piers, begun through the winter ice, were driven forty to fifty feet through the river bottom and there anchored. The solid concrete was reinforced with steel. A row of eighty pound rails, set a foot apart all around, the whole structure bound together with concrete, were placed next. Then above the piers, ice-breakers, similarly constructed, were planted.
It was conceded in the beginning that no false work would stand against the battering ice. Therefore the work of connecting the piers with the steel road-way must be done in winter. It was a cruel and trying task. The weather did its worst. It was bitter cold. Snow storms were practically continuous. The piercing wind blew sixty to ninety miles an hour and the fine particles of snow hurled by the gale cut and stung one's face like shot.
When the last span was almost in place there came a most appalling moment. The "false work," as the supports are technically called and which in this case consisted of two thousand piles driven forty feet into the bottom of the river, suddenly moved fifteen inches! The ice, a solid sheet, was borne on a twelve knot current. Into it the piles had been frozen as solidly as a rock. The spring break-up had begun in the river. The ice-cap, lifted twenty feet above its winter bed, began to move!
The false work with its mass of unfinished steel was fifteen inches out of plumb. Not to get it back meant that communication with the other side could not be established that winter. The engineers recognized that at any moment the whole span, supports and all, might be carried away. The magnitude of the fight they would have to put up in order to prevent this was realized by all of them. But they determined not to lose heart.
