GOLDEN EARS BRIDGE
Location:Langley to Maple Ridge, BC, Canada Description:The main bridge of the Golden Ears Crossing consists of a 5-span continuous 968 m (3175 ft.) long hybrid extradosed bridge with two navigation spans. It comprises 3 equal main spans of 242 m (794 ft.) with side spans of 121 m (397 ft.). The deck of the main bridge is composite steel and concrete utilizing precast concrete deck panels and simple prefabricated steel elements. The main girders, vertical concrete pylons and cables stays act in two parallel single vertical planes. The main pylons utilize a shallow transverse crossbeam hidden within the depth of the deck section to provide transverse frame action. This arrangement permits the use of a single access/maintenance gantry for the full length of the main crossing. The cable-stays are arranged at a relatively flat angle in a simple harped configuration resulting in low (40 m/131 ft.) slender pylons above deck level. The approaches to the main bridge total 1.4 km (0.9 mile) consisting of 600 m (1968 ft.) on the north and 842 m (2762 ft.) on the south. They comprise concrete precast prestressed girders with a concrete deck. Owner:TransLink Client:Golden Crossing Group (JV led by Bilfinger Berger and CH2M Hill) Scope of Work:Buckland & Taylor Ltd. developed the conceptual, preliminary and detailed design of the main bridge and approaches. We are currently providing erection engineering for the construction of this
Design/Build/Finance/Operate/Maintain bridge. The estimated year of completion is 2009.
