A multimillion-dollar bridge that is considered an engineering pride in northern Vietnam is causing a sense of danger amongst many drivers with its palpably bumpy surface, just two months after it opened to traffic.

Drivers’ reports of the unevenness surfaced right on the inauguration day of the 5.4-kilometer-long Bach Dang Bridge in Quang Ninh, a coastal province around 150 kilometers northeast of Hanoi.

The defect can be seen on both carriageways.

The cable-stayed bridge, costing over VND7.2 trillion ($310 million), has three H-shaped pylons and opened on September 1.

It was then hailed by the transport ministry and local administration as a notable all-domestic feat, as it was designed and built by Vietnamese engineers only.

After reports from the public, local media said as the speed limit is 100 kilometers per hour, the wavy surface tended to generate an impression of treacherous driving conditions.

But the provincial authorities later dismissed such claims as wrong, citing strict quality inspections during the construction.

Nguyen Tien Oanh, deputy director of the bridge’s developer, put the undulation down possibly to a difference in height from one bridge segment to another.

The company found the problem in April, way before the opening ceremony, but those involved in the project at the time advised delaying the repair work until the bridge had been put to use and its performance monitored, Oanh underlined.

He declined to comment on the doubt that technical requirements were not met, but said vehicles can now safely cross at the maximum safe speed.

Engineers are scheduled to reexamine the structure to pinpoint the causes before efforts of fixing it begin, officials said.
