Which country has the most bridges?

It's difficult to determine which country has the most bridges as data on the number of bridges in different countries can be inconsistent and hard to compare. However, China is known to have built many large and extensive bridge systems in recent years, connecting many of its cities and regions. The Chinese government has invested heavily in infrastructure development, including the construction of bridges, highways and high-speed railways, which has led to the construction of many new bridges in the country.

What is the most expensive bridge?

It's difficult to determine the most expensive bridge as the cost of building a bridge can vary greatly depending on a number of factors such as location, materials used, and length of the bridge. However, some of the most expensive bridges built include:

  1. The Hong Kong-Zhuhai-Macau Bridge in China, which cost $20 billion USD to construct.
  2. The Øresund Bridge between Denmark and Sweden, which cost $8.5 billion USD to construct.
  3. The Millau Viaduct in France, which cost $396 million USD to construct.
  4. The Akashi Kaikyō Bridge in Japan which cost around $3 billion USD to construct.
  5. The Great Belt Fixed Link in Denmark, which cost $3 billion USD to construct.

It is important to note that these cost are approximate and may have changed over time due to various reasons such as inflation, currency fluctuation and additional costs added during the construction process.
