Nghe An and Ha Tinh are two provinces that belong to the same cultural region of Nghe An, but are separated by the immense Lam River. The section of Lam River flowing through the Ben Thuy area, located on National Highway 1A, is about 650m wide. Due to the need for a permanent bridge with a wide bridge deck, bridges connecting the banks of the Lam River were gradually built.

In 1986, Ben Thuy I bridge was started construction. This is the first bridge on National Highway 1A connecting Vinh City (Nghe An) and Nghi Xuan district (Ha Tinh).

In May 1990, Ben Thuy 1 bridge was inaugurated and put into use.

The project has a length of 630.5m with 13 spans. The bridge was built using old technology with a steel truss structure.

One end of Ben Thuy bridge on the side of Vinh city (Nghe An) currently has a BOT toll station collecting tolls for cars passing through.

After Ben Thuy I bridge, in March 2010, the Ben Thuy II bridge project was started to connect from Hung Loi commune (Hung Nguyen district, Nghe An) to Nghi Xuan district (Ha Tinh). The project was completed in 30 months, with a total investment of more than 1,200 billion VND.

This is a project that contributes to solving the overload situation of Ben Thuy I bridge, in accordance with the national and regional road traffic development planning; Improve the operational efficiency of the Vinh bypass route.

The highlight of Cua Hoi Bridge is that the main span uses an Extradosed balanced cantilever structure - the most modern bridge construction technology in Vietnam today.

Cua Hoi Bridge has 22 pillars and 85 Super-T beams. Main bridge width is 18.5 m, access bridge width is 16 m. The total investment of the project is 950 billion VND.

The architectural highlight of the bridge is located on top of the concrete column with a lotus bud symbol. This concrete column is also where the cable stays leading downwards are installed.

The road part of the project is designed according to level 3 plain road standards, the road bed is 12 m wide, the road surface is 11 m, including two motor vehicle lanes and two mixed vehicle lanes, design speed of 80 km/h. .
