This paper examines the challenges faced and lessons learned relating to slope stability, foundations, girder design and erection, and environmental issues, during the construction of the North Saskatchewan River Bridge. Scheduled for completion in 2005, these twin four span (80-100-100-80 meters) steel girder structures are the only new bridges of this type and length constructed in Alberta in recent years. Design procedures and construction techniques that are new for the Edmonton area include tangent pile walls, caisson casings, large concrete pours, and girder erections. Challenges encountered on this project include approach fills that are prone to sliding, the effects of bridge curvature on final girder camber, and the stability of girders during erection.
