The new Walterdale Bridge will be a signature structure in the heart of Edmonton’s river valley, respecting the beauty and history of the setting, and creating a landmark gateway to the City’s downtown. The bridge will replace the existing three-span structural steel truss bridge that was constructed between 1912 and 1913 to carry two lanes of roadway traffic and a street railway across the North Saskatchewan River. Unique extradosed, arch and cable-stayed bridge alternatives were compared to a more conventional girder bridge alternative for the replacement, with a through-arch bridge spanning 206 m from bank to bank being selected as the preferred alternative. The replacement bridge will carry three lanes of northbound traffic on an alignment to the east of the existing structure. It will have a wide sidewalk to the west of the roadway and a separate shared use path to the east. The $155 million project has included an extensive public consultation program along with historical resources and environmental assessments. Construction commenced in early 2013 and is currently underway.
Pre-registration is required.
