The cross-sea bridge refers to a bridge across the strait. The span of such bridges is generally long. The short cross-sea bridge is thousands of meters, and the long-crossing bridge can reach dozens of kilometers.

Therefore, the construction of the cross-sea bridge has higher requirements for technology, which is the embodiment of top bridge technology.

The design of the bridge, especially the cross-sea bridge, is a very complicated system of engineering, involving all aspects of factors. Sometimes different factors also bring contradiction.

The final plane wiring and pavement elevation are relatively optimal designs after careful consideration.

There are these attractive cross-sea bridges around the world, and each of them is amazing. Today, let's get to know these stunning world bridges.

Seto Bridge in Japan

Japan's Seto Bridge, spanning the Seto Inland Sea between Honshu and Shikoku Island, consists of three cable Bridges, two cable-stayed Bridges, and a truss bridge, with a total length of 37.3 kilometers, including 13.1 kilometers over the sea, making it the world's longest cross-sea bridge at that time.

Construction of the bridge, which began on October 10, 1978, took nearly 10 years and $8.46 billion. The bridge opened to full traffic on 10 April 1988.

The Seto Bridge in Japan is a dual road and railway bridge with a four-lane expressway on the upper level and a railway bridge on the lower level.

In addition, the longest suspension bridge on Japan's Seto Bridge (the distance between the two towers) is 1,100 meters long.

Chesapeake Bay Bridge

The Chesapeake Bay Bridge, which spans 37 kilometers between Maryland and Virginia, was opened to traffic in 1964 and is known as "one of the seven wonders of the modern World."

The Chesapeake Bay Bridge is a bridge over the sea, like a promenade on the water between the Chesapeake Bay and the Atlantic Ocean.

If you stand on the artificial island in the middle of the bridge, you can enjoy spectacular views of the world's busiest shipping lane, as well as fishing, dining, and souvenir shopping. In addition, the bridge is opened once a year for the public to walk or bike.

King Fahd Bridge

The King Fahd Bridge is located in the Gulf of Bahrain in the Persian Gulf. It is a 26-kilometer cross-sea highway bridge connecting Bahrain and Saudi Arabia.

Construction of the bridge began in 1981 and took more than four years. The bridge opened to traffic on November 25, 1986, at a cost of $1.2 billion.

The bridge is made up of five connected Bridges, with the middle bridge No. 3 in the main fairway, leaving a huge boat hole with a span of 150 meters for ships to pass through.

The bridge deck has 4 lanes and sidewalks on both sides, allowing 30,000 vehicles to pass through daily.

The Erasmus Bridge

The Erasmus Bridge is located in the Netherlands and is the highest bridge in the Netherlands. Known as the Swan Bridge, it has a sleek shape, like an elegant white swan wandering nobly over the Maas River.

The Swan Bridge is 139 meters high and 802 meters long, making it the longest cable-stayed bridge in the world at that time. The cable-stayed bridge is supported by steel cables suspended from the pylons.

The Brooklyn Bridge

The Brooklyn Bridge, which spans New York, was opened on May 24, 1883. The 1,834-meter-long bridge, which is lifted 41 meters above the water by tens of thousands of steel cables, was the first steel bridge built in the world.

When it was built, the Brooklyn Bridge was hailed as one of the world's seven epochal architectural wonders of the Industrial Revolution.
