#### Golden Gate Bridge

##### Overview
The Golden Gate Bridge is a suspension bridge that spans the Golden Gate, the one-mile-wide strait connecting San Francisco Bay and the Pacific Ocean. Linking the city of San Francisco to Marin County, it is often celebrated as one of the most recognizable symbols of the United States and a remarkable feat of engineering.

##### History
The construction of the Golden Gate Bridge began in January 1933 and was completed in April 1937. It was designed primarily by Joseph Strauss and Irving Morrow. During the time of its completion, it was both the longest and tallest suspension bridge in the world, measuring approximately 1.7 miles (2.7 kilometers) in total length, with a main span of 4,200 feet (1,280 meters).

##### Design and Features
The bridge is famous for its towering Art Deco style towers and striking International Orange color, a hue specifically chosen to enhance its visibility in the foggy weather characteristic of the San Francisco Bay. The engineering advancements incorporated into the bridge were groundbreaking at the time, including the use of deflection theory which allowed it to flex in response to wind pressures.

##### Cultural Impact and Significance
The Golden Gate Bridge has become more than just a route for transportation; it is a symbol of innovation, resilience, and American spirit. The bridge has appeared in numerous films, photographs, and TV shows, reflecting its iconic status in American popular culture. It also draws millions of visitors each year who come to marvel at its breathtaking views and architectural beauty.

#### Gwangandaegyo Bridge

##### Overview
The Gwangandaegyo Bridge, also known as the Diamond Bridge, spans the waters of Busan, connecting the Haeundae-gu district to the Suyeong-gu district. It is renowned for being South Korea's longest bi-level bridge over the ocean.

##### History
Construction of the Gwangandaegyo Bridge began in 1994 and it was opened to the public in December 2002. The bridge was built to ease traffic congestion in the rapidly growing city of Busan and to boost the local economy by enhancing access to the beaches and tourist sites around Haeundae.

##### Design and Features
The Gwangandaegyo Bridge measures approximately 7.4 kilometers in length, making it one of the longest bridges in South Korea. Its design features a double deck structure with the upper level serving vehicular traffic while the lower level is reserved for pedestrians during special events. The bridge is also equipped with thousands of LED lights, which create a spectacular light show every evening, illuminating the bridge in various colors.

##### Cultural Impact and Significance
The Gwangandaegyo Bridge has played a significant role in transforming Busan's landscape, offering not just a transportation route but becoming a focal point for cultural festivals and events.
