History of The MacKay Bridge

The opening of the A. Murray MacKay Bridge on July 10, 1970 was a historic event for the Halifax Dartmouth Bridge Commission. The construction of the second bridge across Halifax Harbour took about three years, and drew international interest due to its design and the engineering techniques that were used for the first time in North America.

The MacKay Bridge was named after the Commission’s former Chairman, who sat on the board from 1951 to 1971.

Mr. MacKay was instrumental in the construction of both the Macdonald and MacKay Bridges, as they were both opened during his tenure. Also, at the time, Mr. MacKay was the Chief Executive Officer of Maritime Tel & Tel.
