The focus of strand jacking equipment is moving from merely safety to safety, sophisticated applications, speed, and cost. The author describes strand jacking applications on the 1927 Carquinez Bridge, the Miraflores Viaduct, Bangkok's Industrial Ring Road, Rouen, France's sixth bridge, Germany's Nord Ostsee Kanal, the Milford Haven bridge, Hong Kong's Stonecutters Bridge, and Abu Dhabi's Sheikh Zayed Bridge.
