Structure
The two towers were 180 feet (55 m) high and the distance between them spanned by a truss was 1,000 feet (300 m). The weight of the cables suspending the girder was 250 tons. The underside of the girder was 82 feet (25 m) above the high water level. The transporter car was 55 feet (17 m) in length and 24 feet 6 inches (7.5 m) in width and was designed to carry 4 two-horse farm waggons and 300 passengers. A shelter was provided for the passengers. The bottom of the car was 12 feet (3.7 m) above high water level and it cleared the ship canal wall by 4.5 feet (1.4 m). It was suspended from a moving trolley 77 feet (23 m) in length. In conditions of reasonable weather and load the journey took 2.5 minutes. The driver was sited in a cabin on top of the car from which he had an uninterrupted view in all directions. In order to provide power for motors on the trolley a power house was built within the tower on the Widnes side. Approach roads of 320 feet (98 m) on the Widnes side and 470 feet (140 m) on the Runcorn side were built.

Famous quotes containing the word structure:
“When a house is tottering to its fall,
The strain lies heaviest on the weakest part,
One tiny crack throughout the structure spreads,
And its own weight soon brings it toppling down.”
—Ovid (Publius Ovidius Naso)
“Science is intimately integrated with the whole social structure and cultural tradition. They mutually support one other—only in certain types of society can science flourish, and conversely without a continuous and healthy development and application of science such a society cannot function properly.”
—Talcott Parsons (1902–1979)
“What is the structure of government that will best guard against the precipitate counsels and factious combinations for unjust purposes, without a sacrifice of the fundamental principle of republicanism?”
—James Madison (1751–1836)
