The original plan for a cable-drawn bridge train had not been abandoned. It was just that the bridge would now have enough added strength to accommodate the future, which, it was quite naturally presumed, would involve some sort of railroad. The presumption was mistaken; but for different reasons nobody could have guessed at then—the advent of the internal combustion engine and the automobile, mainly—the decision would turn out to be the right one. As a result, the bridge would remain in service for another fifty years before any major alterations in the superstructure became necessary.
