| Abstract: |
The three level system interchange connecting Northeast Anthony Henday Drive and Yellowhead Trail implement two flyover ramp bridges. To improve construction efficiencies, the contractor team sought implementation of continuous chorded (kinked) girders rather than conventionally curved girders to accommodate the curved ramp geometry. The multi-span structures comprised of kinked straight I-girders, forming horizontally curved alignments, imposed unique design challenges that were not explicitly addressed within the Canadian bridge code. This paper showcases the two flyover bridges; a 315 m long five span bridge with a radius of 340 m and a 415 m long six span bridge with a 347 m radius. Design challenges and considerations encountered during the design and construction are presented. |
