The main river bridge concept for the Golden Ears project is an adaptation of the Alex Fraser cable-stayed bridge, designed by our consulting associates, Buckland & Taylor. The Alex Fraser, completed in the 1980s, spans the Fraser River west of the Golden Ears crossing, and connects the municipalities of Richmond and New Westminster (on the north shore) with the municipality of Delta.

When it opened in 1986, the Alex Fraser was the longest cable-stayed bridge in the world. Golden Crossing Constructors have used their international experience in bridge construction to update the Alex Fraser concept, creating a much lower-profile bridge design.

Improvements in design will allow for more rapid and more accurate assembly of steel and construction of the cable anchorages. The deck framing system, made of a composite of materials, is very light, reducing the seismic load on the substructure and foundations.

One substantial technical challenge in this project was to develop a foundation design that will allow for timely and cost-effective construction in the deep layers of soft silt of the Fraser River.

The design selected will make use of large-diameter bored piles. These are new to British Columbia, but were recently used by engineers from the project team on the My Thuan Bridge in Viet Nam.

The construction process required to sink these piles requires a minimum of specialized equipment compared with more conventional methods, and it has less impact on the marine environment.
