Better Mobility in Da Nang

The Tran Thi Ly Bridge is a concrete cable-stayed bridge with an overall length of 731 meters, a width of 34.5 meters, and the main span that is 230 meters long. Its single inclined tower is 145 meters high and cables fan out on either side. The bridge has six lanes for traffic plus pedestrian sidewalks on both sides. The bridge spans the Han River in the center of the city of Da Nang in an east-west direction. Passenger and goods transport is now improved between the Han River’s west coast and the east coast’s tourist area, connecting Da Nang city with the Dien Nam-Dien Ngoc industrial zone in the Quang Nam province.

The bridge construction started in April 2009 and was officially opened to traffic on 29 March 2013.

Meeting Client’s Needs

One of the project targets was to provide a new link from the inner city to the port of Da Nang. The client also wanted a landmark bridge which would attract visitors to the area. The unusual bridge design, particularly the single inclining tower with cable arrangements, presented a number of technical challenges.

Creating a Unique Design

A cable-stayed bridge design was chosen for this project. The inclined tower and the cables give it a unique design. We would usually have specified steel or composite structures for the main span of a bridge of this kind, but as concrete is a more widely used material in Vietnam, the team adapted the design to accommodate a concrete structure.

Due to the weight of tower and the weight of superstructure, the bearings under the tower are among the biggest spherical bridge bearings ever fabricated. The western abutment is designed as a ballast load for the heavy 230 metre-long main span. 

Da Nang city now has a landmark as well as a new bridge connection over the river. The Tran Thi Ly Bridge, the fifth bridge built over the Han River, reduces traffic congestion in Da Nang; advances Da Nang's position as a core city of the country’s central and highlands region; and, as a “must-see” feature, helps to boost the city’s tourism.
