Design and Construction of the Duggan Bridge

The Duggan Bridge serves as a major link for pedestrians, cyclists and eastbound motorists on Saskatchewan Drive over historic Fort Hill Road with a panoramic view of the North Saskatchewan River and downtown Edmonton. The original bridge was a reinforced concrete open spandrel arch constructed in 1957 crossing a historic road in a ravine that originally provided access to the ferry crossing the North Saskatchewan River. Since the mid-1990s, the bridge has undergone a series of assessments & repairs with major rehabilitation and superstructure replacement in 2000. The most recent repairs in 2018, and annual inspections, permitted the bridge replacement to be postponed by up to five years to coincide with other planned major bridge works in the area. However, in the spring of 2020, the City of Edmonton decided to fast track the detailed design and construction with targeted completion by fall of 2021. Preliminary design was completed in late 2019 and included review of five replacement options against various evaluation criteria. The chosen replacement structure was a Single Span Haunched Steel Plate Girder Bridge.

 The detailed design phase was accelerated to allow construction award in fall of 2020 so construction could be completed in one year. Early contractor involvement occurred with a constructability workshop to identify design features to mitigate schedule risk. Piling was identified as a major project risk, and led to the selection of a semi-integral superstructure supported on a single row of piles. The final design accommodated two lanes of eastbound traffic in between a sidewalk and multi-use path. The multi-use path overlooking downtown Edmonton featured a significant cantilever lookout area at the centre of the bridge. Furthermore, an additional design challenge was designing secant pile retaining walls needed to protect the foundations of adjacent high rise residential buildings. The bridge was completed on time, on budget and opened to the public in October 2022.

The presentation will look at design challenges, approach to construction, and discuss key take-aways from the delivery of this project.
