During recent storm Noul, the middle span of the Nguyen Van Troi pedestrian bridge spanning the River Han in Da Nang was vertically lifted to allow fishing vessels to pass under to seek safe shelters from the storm.

These exciting images of the bridge with its middle lifting span have captured a great deal of public attention.

Let's take a look at the operation of the Nguyen Van Troi vertical lift bridge through amazing photos captured by our reporter Xuan Son.

The Nguyen Van Troi Bridge with its middle lifting span

The Nguyen Van Troi Bridge was installed a bridge lifting and monitoring system in 2015.

A jack-up system is a custom-developed multi-point lifting system. Such typical system includes four jack-up towers positioned under each corner of a load. The four-tower setup has a lifting capacity of 400 metric tons (equivalent to 100 metric tons per tower).

The jack-up system has the lifting speed of 0.233 m/min.

The lifting span is 36.45m in length.

Picture taken at the vertical lifting bridge on 19 September by Nguyen Dinh Tuan, a resident of Cam Le District. Tuan said that he has lived in Da Nang for 6 years and this was the first time he had seen the middle span of the Nguyen Van Troi pedestrian bridge in Da Nang vertically lifted.

The Nguyen Van Troi Bridge was built in 1965 by the Americans to connect the western and eastern sides of the Han River to transport weapons of war from the Tien Sa Port to the inner city. Till date, the bridge has kept its original design as witness to a part of Da Nang’s history. It was converted into the city’s pedestrian-only bridge in 2013 in a bid to create a new place to visit in Da Nang.
