2. What is Thi Nai Bridge famous for?

2.1. The former longest sea-crossing bridge in Vietnam

Construction of Thi Nai Bridge began in 2002 and was completed in 2006. With its distinctive design and impressive length, it has long been a source of pride for the people of Quy Nhon. Stretching nearly 7 kilometers, the bridge features a main part of about 2.5 kilometers across Thi Nai Lagoon and five smaller parts over the Ha Thanh River. The main part is over 14 meters wide and consists of 54 spans. For more than a decade, it held the record as Vietnam’s longest sea-crossing bridge until the Tan Vu - Lach Huyen Bridge was built in 2017 in Hai Phong.

2.2. Strategic transport significance

More than just a landmark, Thi Nai Bridge is a vital transport route in Quy Nhon. It is linked with National Road 19, National Road 19B, and several provincial roads. It connects to Quy Nhon Port, opening up opportunities for international trade for the South Central Coast, the Central Highlands, and even markets in northeast Cambodia, southern Laos, central Thailand. 

The construction of Thi Nai Bridge also ended the isolation of Phuong Mai Peninsula - which was once accessible only by boat. It makes traveling to the peninsula easier for both locals and tourists, expanding Quy Nhon’s development to the east and north.
