What is a transport bridge?

The transport bridge is a type of bridge with a movable platform suspended above the water surface that carries people or cars from one side to the other. It is designed to allow the ships to pass while the platform is off the road. Despite its practical use, little of its kind remains today.

also called ferry bridge or aircraft transmission bridge, the Bridge Transporter uses a large portable road pulled by thick cables to transmit people and a limited number of vehicles. To ensure that there are no accidents, it requires constant human attention due to its interaction with ships. Its operation time also depends on weather and water conditions. Its origin springs back to the parachutes of medieval Europe, where they served as a defense mechanism for cities and castles. To lift the wooden platform up and down, anti -rotary and reel were used, allowing the allies and maintaining enemies outside.

Ferry Svatonkage began to be used for the first time at the end of the 19th century. During World War II was the first French Trand the subject bridge over the Seina River destroyed to stop the progress of German soldiers. Only two of them were built in the United States, one in Minnesota and one in Chicago. The Vizcaya bridge in Spain, which was the first ever -transport bridge, was declared an educational, scientific and cultural organization (UNESCO) in 2006.

Runcorn-Widnes, one of the first moving bridges in England, could cross the Mersey River in two and a half minutes. At that time it was the main innovation and for centuries it required numerous improvements to be functional. In 1958 he transferred over two million passengers and a quarter of a million vehicles per year. Bad weather caused many closures because a portable car had no ability to doc. She survived until 1961, when she was demolished - for a larger amount than to build - to make a way for a new road bridge.

with a rapid rise in cars in the 20th centuryThe transport bridges were largely considered to be obsolete. Most of them cannot handle the volume of traffic and their high maintenance is impractical for most cities. These bridges were replaced by more comfortable and discarded from production. The United Kingdom today has the most surviving examples with four, although only three are still used.
