Da Nang is known as the city of bridges, not only because of the number of bridges spanning the Han River but also because of the uniqueness of these works.

Han River starts from the river junction between Cam Le, Hai Chau, Ngu Hanh Son districts, is the confluence of Cam Le river and Vinh Dien river and flows into Da Nang bay near the entrance channel to Tho Quang wharf. Han River is only about 7.7km long but has 6 bridges across it.

These bridges are not only important for transportation but also an architectural highlight of the city with unique features that are rarely found anywhere else in our country.

Thuan Phuoc Bridge started construction on January 16, 2003 with an investment of nearly 1,000 billion VND from the State budget.

The bridge is located in a special location, where the Han River flows into the sea.

Thuan Phuoc bridge is 1,856m long, 18m wide with 2 towers about 80m high from the pile base, 3 hammock spans of 655m long. This is the longest and most unique hammock bridge in Vietnam.

Built in a special location with complex estuary geology, the construction of foundations, abutments, and bridge piers, especially the foundations of the two towers of Thuan Phuoc bridge, encountered many difficulties. The bridge has a large architectural height and is located at an estuary, so the influence of wind also affects the construction progress. The bridge was inaugurated in 2009 after 6 years of construction.

Han River Bridge is one of the first bridges across the Han River, connecting the two main roads of Da Nang, Le Duan Street on the west bank and Pham Van Dong Street on the east bank of the city. The bridge is 487.7m long, 12.9m wide with 11 spans, each span is 33m long, prestressed reinforced concrete structure and 2 cable-stayed spans with a total length of 122.7m, main bridge girder and tower structure steel, bridge deck made of reinforced concrete.

The special thing about the Han River Bridge is that it is the first swing bridge designed and constructed by Vietnamese engineers and workers. The bridge has the ability to rotate the span 90 degrees compared to the original, creating 2 waterways for ships to pass through. Shooting time is usually at midnight. Han River Bridge started construction on September 2, 1998, completed on March 29, 2000.
