The 'Big Lift' Project of Macdonald Bridge Re-Decking, Halifax, Canada: A Dynamic Traffic Assignment Model

The Angus L. Macdonald Bridge is one of the two suspension bridges linking twin cities Halifax and Dartmouth in NS, Canada. The Macdonald Bridge has been a vital link of the Halifax transportation network for its continuous 24/7 access across the Halifax Harbour. The bridge remains very busy in peak periods during the day due to its proximity to Downtown Halifax and Dartmouth. Only light vehicles are permitted to cross the bridge, while truck and other heavy vehicles use the wider Mackay Bridge. The bridge not only accommodates a large commuter traffic volume, but also facilitates pedestrian and bicyclist that cross the Halifax harbour. However, after being operational about 60 years, the time has come to replace the entire deck slab of the Macdonald Bridge for an extended service life and a minimum frequency of maintenance. At the beginning of 2015, the Halifax Harbour Bridge Commission launched the “Big Lift” project in order to replace 46 deck segments within 18 months, a total worth of $150 million. Although this is undoubtedly a necessary transportation infrastructure development in Halifax Regional Municipality (HRM), it will likely affect the vicinity of the bridge, traffic flow on Mackay Bridge, daily travel activity and traffic operation, transit routes and schedules.
