Deck Replacement of the Angus L. Macdonald Suspension Bridge
The Angus L. Macdonald Bridge, a major suspension bridge that crosses Halifax Harbour in Halifax, Nova Scotia, was opened for traffic in 1955. The bridge deck has reached the end of its service life, and the design of the new bridge superstructure and its replacement sequence have been completed. The entire suspended structure and hangers will be replaced sequentially during night closures while the bridge will be opened for traffic during daytime. The erection sequence has been supported by sophisticated automated erection analysis models which take into account the geometry of the existing bridge, positioning of the erection equipment on the deck, and necessary hanger and strand jack adjustments. Significant wind tunnel testing and analysis have been performed to ensure aerodynamic stability of the bridge during erection and in its final condition.
