Location

The previous Walterdale Bridge (formerly called the 105 Street Bridge, renamed in 1967) was a steel grating-decked truss bridge. It was built in 1913 by the Dominion Bridge Company and was named after John Walter, an early settler who ran a ferry at this approximate location. The neighbourhood Walterdale at this location was also named after John Walter.

Demolition of the 1913 bridge began in October 2017 after the decking, sidewalks, and utilities had been removed, and was completed by the end of that year.

Planning for the replacement of the 1913 Walterdale Bridge began over a decade before construction on the new bridge started. In 2001, an Edmonton City Council committee rejected a $190-million proposal for a tunnel under Saskatchewan Drive to directly connect the new bridge to Gateway Boulevard. Planners considered both a four-lane one-way bridge and a five-lane bridge with a single southbound lane to connect the area to Kinsmen park.

Construction began on a replacement bridge in early 2013 and was scheduled to be completed in late 2015; however, it did not open (two lanes only) until September 18, 2017. The contractor faced over $10 million in penalties for the delay. The new bridge has three lanes for northbound vehicular traffic and improved pedestrian and cyclist crossings. Roadway and trail links north and south of the bridge were partially complete, and the pedestrian access and all lanes opened on September 29, 2017.

The new bridge is east of the original bridge site, and is supported by concrete thrust blocks on the banks of the river, eliminating the need for piers. The arches are 56 m (184 ft) tall.
