WSP-designed Tran Thi Ly Bridge opens in Vietnam

WSP is the designer of an imposing cable-stayed bridge opened with grand ceremony in the city of Da Nang, Vietnam, on 29 March 2013.

 

The 731m long Tran Thi Ly Bridge is a striking new landmark for Da Nang City, characterized by its chic red cables fanning out on either side of the bridge and its dramatic illumination. 

“The client wanted a landmark bridge, which presented us with a number of technical challenges,” says Esko Järvenpää of WSP Finland, lead consultant and designer of the Tran Thi Ly bridge.

One of the most unusual features of the design is the single, inclined tower, which, at 145m high, is the highest backwards-leaning single pylon for a cable-stayed bridge. In addition the bearings for the vertical loadings located at the pier under the pylon are the biggest spherical bridge bearings ever fabricated.

With six lanes for traffic, plus pedestrian sidewalks on both sides, the 34.5m-wide concrete deck is supported by single plane cables along the middle line of the superstructure in the main span. It is thought to be the widest concrete bridge deck in Asia to be suspended in this way.

The Tran Thi Ly bridge crosses the river Han in the centre of Da Nang city. WSP Finland’s involvement in the project started with success in winning an international bridge competition. The firm went on to undertake the architectural, basic and detailed engineering design for the bridge. 

The bridge design has also been recognized through the award of an international Bentley prize under the ‘Innovative bridge planning’ category.
