1. Overview of Thi Nai Bridge
Also known as Nhon Hoi Bridge, Thi Nai Bridge is a standout landmark in Quy Nhon, connecting the city with the Phuong Mai Peninsula (part of the Nhon Hoi economic zone). Construction began in 2002, and the bridge was completed in 2006, with an investment of nearly 370 billion VND.
The bridge’s structure includes the main span crossing Thi Nai Lagoon, five smaller bridges over the Ha Thanh River, and approach roads on both ends. In total, including the approach roads, the bridge stretches nearly 7 kilometers, with the main span measuring about 2.5 kilometers. The bridge is 14.5 meters wide, consisting of 54 spans, each with a length of 120 meters.
When it was inaugurated, Thi Nai Bridge was the longest sea bridge in Vietnam. After more than a decade, it was surpassed by the Tan Vu – Lach Huyen Bridge (Hai Phong). Today, this bridge remains the longest sea bridge in Binh Dinh Province, symbolizing the province’s prosperity and growth.
