Gwangan Bridge, also known as Diamond Bridge, stretches over the waters of Busan, linking the districts of Haeundae and Suyeong-gu. Opened in 2003, the bridge spans approximately 7.4 kilometers in length, making it the second-longest bridge in South Korea. Its design comprises a two-tier bridge system with vehicles traveling on the top while the lower level is reserved for potential future public transportation options, which is part of Busan's ambitious urban planning. The impressive engineering feat provides significant traffic relief and offers a scenic route with panoramic views of the surrounding coastline and city skyline. The Gwangan Bridge becomes a focal point for both photography enthusiasts and tourists, especially at night when it is illuminated by thousands of LED lights creating stunning visuals. The light shows are often themed, varying according to festivals and seasons. Moreover, the bridge creates an iconic backdrop for Gwangalli Beach, which is famous for its fine sand and vibrant nightlife, making the surrounding area a popular destination for locals and visitors alike.
