Why Are Viaducts Called Viaducts 2?

Viaducts are a type of structure that crosses a large distance. Some are single span, while others may be multi-span masonry structures, or concrete arches. Trenchways, meanwhile, consist of several short spans supported by bents. They may be single or double-decked, and are used for railroads and other large vehicles. Although older timber structures are still used, modern construction often favors concrete beams or box-girders on steel piles.

In the mid-19th century, engineers began constructing viaducts. They were a convenient way to connect major cities. Originally, they served as bridges, and were often used by trains to cross rivers. Today, these structures are a popular destination for tourists and locals alike. Many of the world’s largest viaducts were constructed in Europe.

The Colne Valley Viaduct is the UK’s largest railway bridge. Construction on the Colne Valley Viaduct will begin in early 2021. Almost 300 piles will be needed to build the structure, which will span the River Colne and the Grand Union Canal. The structure will be low to the ground, which will maximize views across the landscape. The project is a joint venture of Bouygues Travaux Publics, Sir Robert McAlpine, and VolkerFitzpatrick.

In the spring of 1871, the Cleveland City Council approved the construction of the viaduct after a petition was presented. It included sixty-seven signatures and was signed by F.W. Pelton and sixty-seven others. Another prominent citizen of Cleveland, John Huntington, introduced a resolution to construct a viaduct, and later became a member of the committee that supervised its construction.

A third viaduct was planned, but World War I put an end to all plans. Afterward, the Van Sweringens Company built a terminal complex at the foot of Huron Road and the Shaker Square development with Rapid Transit. The terminals suggested that the road from Huron Avenue to Lorain Avenue would soon be a major thoroughfare, carrying heavy traffic to downtown Cleveland. The City Planning Commission recommended that the bridge be constructed as soon as possible.

Many public road and railway modernizations are underway. The goal is to meet the demands of increasing service loads and new terms of use. Many bridges on these modernized routes require restoration or reinforcement. The main reason is poor technical condition. A restored bridge structure must be compliant with specific requirements. Moreover, many of these structures are considered historic objects, protected by conservation regulations.

While the Inner Belt Bridge, which was built in 1909, is one of the largest bridges in the United States, it is also the widest in Ohio. In addition, it was the largest contract awarded by the Highway Department. It features eight lanes of traffic and accommodates 95,000 vehicles a day. It also has three-foot safety walks. Its width is 116 feet, 3 inches.
