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:
“... the structure of a page of good prose is, analyzed logically, not something frozen but the vibrating of a bridge, which changes with every step one takes on it.”
—Robert Musil (1880–1942)
“For the structure that we raise,
Time is with materials filled;
Our to-days and yesterdays
Are the blocks with which we build.”
—Henry Wadsworth Longfellow (1809–1882)
“The question is still asked of women: “How do you propose to answer the need for child care?” That is an obvious attempt to structure conflict in the old terms. The questions are rather: “If we as a human community want children, how does the total society propose to provide for them?””
—Jean Baker Miller (20th century)
