Yunnan Bridge

 

Solutions & Technologies

The Honghe Suspension Bridge between Honghe Hani and Yi Autonomous Prefecture in Yunnan Province, South of China was completed within 35 days.

 

Description

This suspension cable bridge is an important project to strengthen the transportation infrastructure and the economic development in the south of Yunnan province and it will be one of the biggest cable suspended bridges with a steel deck done in UHPC in the world: 700m long and 30m width.

 

Optimization

Ductal® Overlay solution was selected due to its capacity to enhance durability and safety, reduce maintenance costs along the bridge life cycle and its quick implementation to respect the tight schedule.

Zurich Airport railway station

The four tracks of Zurich Airport's underground railway station have been renovated and lowered without interrupting traffic.

 

Commodore Barry Bridge

The Commodore Barry Bridge spans over the Delaware River from Chester PA to Bridgeport NJ. Originally constructed in 1969 and named after the Revolutionary War Hero from Philadelphia John Barry. This bridge is a cantilever truss bridge which was commonly built during those times.

 

Delaware Memorial Bridge

In 1951, the Delaware Memorial Bridge was opened to traffic allowing commuters to navigate over the Delaware River on a 3,650 ft (1,112 m) long state-of-the-art suspension bridge.

 

Chillon Viaducts

The Chillon Viaducts have been reinforced by an Overlay of Ductal® UHPC. Thanks to its mechanical characteristics and its durability properties, Ductal® was the only material able to provide an efficient retrofitting preserving the bearing capacity of the bridge, a lower maintenance cost and a quick retro commissioning of an important axis of the Swiss highway network. The two Chillon Viaducts are among the most spectacular infrastructure works of the Swiss highway network. Ductal® was prescribed for the reinforcement of the two decks (2.2 km long by 12 m wide each). The implementation of thin layer of Ductal® (4 cm thick) with rebars, allowed the strengthening of the bridge decks for shear loads, bending, and fatigue while ensuring the waterproofing of the surface.
