India's first sea bridge is called the Bandra-Worli Sea Link. It is a cable-stayed bridge that connects Bandra and Worli in Mumbai.
The first cable-stayed bridge, which is often considered a precursor to modern cable bridges, was built in 1784 in Germany. However, the first true suspension bridge, which utilized cables to support the deck, was completed in 1820 in Scotland, known as the Menai Suspension Bridge. This type of bridge design has since evolved, leading to the construction of many iconic cable-stayed and suspension bridges around the world.
The Batman Bridge, the first cable-stayed bridge in Australia, crosses the Tamar River in northern Tasmania. It was constructed between 1966 and 1968.

The Brooklyn Bridge was the first suspension bridge to use steel for its cable wire and the first to use pneumatic caissons.
The towers are built first. Steel ropes are suspended from the towers. Special machines spin these into strong steel cables. Next, long steel cables called hangers are attached to the suspending bridge. Sections of the deck are lifted into place and fixed to the hangers.
The Brooklyn Bridge, completed in 1883, features a hybrid design of both suspension and cable-stayed elements, supported by two iconic stone towers. Spanning approximately 1,834 feet, it was the first steel-wire suspension bridge and incorporates a unique Gothic-style architectural design with pointed arches. The bridge has a pedestrian walkway above the vehicle lanes, offering stunning views of the Manhattan skyline and the East River. Its distinctive cables and intricate masonry make it a celebrated symbol of New York City.

The Brooklyn Bridge, completed in 1883, is unique for its innovative hybrid design, combining both suspension and cable-stayed elements, which was groundbreaking at the time. It was the first steel-wire suspension bridge and its impressive span of 1,834 feet made it the longest suspension bridge in the world for many years. Additionally, the bridge's Gothic-style towers and intricate stonework contribute to its iconic aesthetic, symbolizing both engineering prowess and the spirit of New York City. Its construction also showcased the resilience and determination of its designer, John A. Roebling, and his son, Washington Roebling, who completed the project after his father's death.
