This upset official calculations severely, and accordingly fresh tenders for a simpler type of bridge were called. The task was thrown open to the world, and celerity of construction was the primordial condition. The British firms re-tendered, but to their disgust they were beaten hopelessly both in regard to the cost of the structure and the time in which it could be erected by the American engineers. The result was that the contract went to a Philadelphia firm. Five weeks after the receipt of the order the steel-work left New York, and within a further few weeks communication across the river was provided by 7 spans of steel, each 147 feet long, resting on cast-iron cylinders.
