Location

The Angus L. Macdonald Bridge the first of two suspension bridges currently linking the Halifax Peninsula to Dartmouth across Halifax Harbour in the Halifax Regional Municipality, opened on April 2, 1955.

It is named after the former premier of Nova Scotia, Angus L. Macdonald, who had died in 1954 and had been instrumental in having the bridge built. The bridge was designed by Phillip Pratley, one of Canada's foremost longspan bridge designers who had also been responsible for the Lions Gate Bridge in Vancouver[1]. The bridges have a similar design, which is most notable in the towers. The contractor was Dominion Bridge Company Ltd.

The bridge sometimes suffers from traffic problems during rush hours as a result of the structure's proximity to the downtown cores of Halifax and Dartmouth, as well as its narrow width. No large trucks are allowed to cross, they must use the larger MacKay bridge instead. Buses are allowed to cross and the bridge is part of several Metro Transit routes. In 2005 the average number of vehicle crossings per day was 37,739.

A modernization project was undertaken in the late 1990s and completed in 1999 which saw the original 2 lanes and 1 sidewalk and utility corridor expanded to 3 lanes, with the centre lane being reversible to assist with traffic flow during peak periods. To reduce the weight of the roadway, asphalt and concrete were removed and special steel plating (an orthotropic deck) was used in its place. New pedestrian and bicycle lanes were attached to the outside of the structure to replace the original sidewalks.

External aesthetic lights were added during the modernization project which saw the bridge's towers lit for the first time on a continuous basis every evening from sunset until midnight. Critics derided the effort as a waste of electricity, given Halifax Harbour's frequent foggy weather conditions. The lighting was estimated by the bridge authority to cost in excess of approximately $50,000/year in 1999.

As of 2007, the bridge charges a toll (75¢, 60¢ with a token or MACPASS electronic toll system) to cross for regular passenger vehicles. Larger vehicles have higher tolls proportional to the number of axles. The Halifax-Dartmouth Bridge Commission is exploring the idea of moving entirely to electronic tolls to avoid handling tokens or cash.
