Over the last decade, Extradosed bridges have become an attractive structural … Faced with environmental, aesthetic and traffic concerns in building a new bridge over the St. Croix River, we implemented a concrete extradosed design, just the second in the U.S. See how we blended the most serviceable aspects of both girder and cable-stay bridge structures in order to achieve our clients' goals and deliver the award-winning design. extradosed bridges emerged in the last two decades as a promising structural system to effectively and economically bridge spans ranging between 100 and 200 m. For such spans the prestressed box girder bridges require deep and heavy deck cross section. In cost wise, allowable stress for cable in cable stayed bridge is always smaller than extradosed bridge type in may design code because of fatigue concern and types of anchor can be chosen for external tendon anchorage systme in extradosed bridge rather than cable stayed bridge type which way more expensive.
