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.
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.
