ELEANOR SCHONELL BRIDGE
The award-winning Eleanor Schonell Bridge across the Brisbane River in Australia connects Dutton Park to the University of Queensland campus. The 20 m (66 ft) wide bridge carries two lanes of traffic and two sidewalks with canopies for pedestrians and bicycles. It is designed to accommodate a future light rail track.
The main cable-stayed bridge consists of a 183 m (600 ft) main span and 30 m (98 ft) and 73 m (240 ft) side spans. Two planes of stay cables in a “harp” arrangement support the steel-concrete composite superstructure. The concrete pylons rest on concrete pile caps at water level. The pile caps are supported by 1.5 m (4.9 ft) diameter bored piles.
SYSTRA IBT developed the structural design for the cable-stayed spans in association with GHD. This design-build project was completed on an accelerated schedule with design starting in February 2005 and construction substantially complete in September 2006.
This project received the 2008 Golden State Award, ACEC’s (CELSOC’s) highest honor for projects engineered in the State of California, and the ACEC 2008 Excellence in Engineering Design Honor Award.
