How long did it take to build the Millau Viaduct?

It took three years to build, was formally inaugurated on December 14, 2004, and opened to traffic two days later, on December 16th. The bridge has been frequently recognized as one of the greatest engineering feats of all time, and it awarded the International Association for Bridge and Structural Engineering's Outstanding Structure Award in 2006. It is also listed as a UNESCO World Heritage Site.

The main span is 1725 feet (520 m), and at its highest point it is 240 feet above the river valley. It consists of 38 individual segments, each weighing about 22 million pounds (10 million kg). Each segment is made up of multiple layers of pre-stressed concrete with vertical steel bars embedded in them. The entire structure is suspended over the valley by 235 large suspension bridges, which connect to it via arches. The longest of these are 150 feet (45 m) and they support the road network on both sides of the viaduct.

The total cost of construction was estimated to be around $70 million dollars at that time. Nowadays, this price would not be unusual for a major highway bridge. Back then, however, it was considered very expensive for its time. Even though France had a national program in place to promote sustainable development until 2003, when it was canceled due to budgetary constraints, the Millau Viaduct is an example of what could have happened if it had been approved for construction.

How many years did it take to build the Donghai Bridge?

The designers devised plans and methodologies for safe and fast off-shore construction, and as a consequence, the bridge was completed in under 40 months, from June 2002 to October 2005. The main span is 830 feet (254 m), with side spans of 456 feet (137 m). It has 29 vertical columns, each one taller than the previous one; this makes it the tallest bridge in Asia. The total length of the bridge is 3,319 feet (1 km).

It crosses the Yangtze River about 100 miles (160 km) south of Shanghai.

The world's longest rail bridge, it connects China's Shanghai to its city of Hangzhou on the upper reaches of the Yangtze River. At 137 meters (459 ft) wide, it is also one of the largest bridges in terms of deck area. The rail line across it runs between Shanghai and Beijing, linking China's eastern and western regions together. The new bridge replaces an old suspension bridge that had been built in 1958 near the same site. That bridge was destroyed when the main tower collapsed during a heavy rainstorm.

The new bridge is a joint venture project between China's Zhejiang Province and Japan's Mitsubishi Corporation.

How long does it take to build a big bridge?

Over a two-week period, each half of the new bridge was installed on-site in only a few nights. The entire project took 14 months to complete, including a three-month winter hiatus. Using traditional procedures, it would have taken three to four years. Advanced techniques used in this project reduce that time frame to just over one year.

The new bridge is called "The Mark Wahlberg" after the actor who helped raise funds for the cause. The foundation says donations will be used to support cancer research and treatment at the Massachusetts General Hospital and Brigham and Women's Hospital in Boston.

Wahlberg was diagnosed with non-Hodgkin's lymphoma in 2016. He has been active in raising money for cancer research since his diagnosis.

The new 0.5-mile-long bridge across the Penobscot River in Westbrook, Maine, opened to traffic in January 2019. It was built by Strauss Construction of New Hartford, Connecticut.

Strauss CEO Tom Strauss said the company was honored to be chosen to build the new bridge.

He added: "We are excited to get started on this project and hope to finish as quickly as possible so that motorists can cross the Penobscot River once again."

How long did it take to build the Tay Bridge?

Three and a half years The bridge took three and a half years to build and cost around PS6 million. The Queen Mother formally inaugurated the completed bridge on August 18, 1966, following the installation of the last 65-ton beam on July 4, 1966. She said at that ceremony that it was "a great pleasure" to mark the beginning of the Royal National Lifeboat Institution's new headquarters building with this important milestone.

The Tay Bridge was an iron, suspension bridge located near Dundee, Scotland. It was the first major steel arch bridge in Britain and one of the first in the world. The bridge connected the towns of Fife and Tayburgh and was used by traffic, including passengers of the popular tourist attraction the Scotchman's Steeplechase.

It was built by John Brown & Sons for the Scottish County of Dundee. The main span was 300 feet (91 m) and there were also two 25-foot (7.6 m) side spans. The central pier was 170 feet (52 m) wide and the total length of the bridge was 810 feet (245 m). It was opened on November 17, 1866, by Prince Alfred, Duke of Edinburgh. The bridge was an immediate success and soon became one of the most popular attractions in Dundee.

However, just five months after its opening, the bridge was destroyed by fire.

How long does it take to build an arch bridge?

The main street bridge's construction began in 2006 and completed in 2010, taking about 4.5 years to complete in full condition. This bridge in China took roughly 5.2 years to build. These are some illustrations of the duration and span of bridge decks. There are many factors that can change this number including type of material used, the size of the crew, the number of days/hours worked per week, weather conditions, etc.

An average-sized arch bridge with a clear height of 120 feet takes about 3 months to construct. A small bridge or one with a clear height of 90 feet takes about 2 months to build. A footbridge or a tunnel bridge takes about 1 month to construct.

The average cost of a single-span arch bridge is $1 million. Multi-span bridges are more expensive because they use structural materials on both sides of the river or stream. Single-span bridges use only one side of their structure for support which makes them cheaper to build. However, they are more susceptible to damage from storms and other environmental factors.

Arch bridges are based on the design of Fontevraud Abbey in France. The abbey was built in 1132 and has been listed as an international monument since 1979. It is considered to be one of the first buildings in Europe to use arches in its structure.
