Location: Halifax, Nova Scotia

Client: Halifax Harbour Bridges

Project Budget: N/A

Beginning in mid-2015, the suspended structure of the Macdonald Bridge will be replaced.  The project includes replacing the road deck, floor beams, stiffening trusses, suspender ropes and all electrical and mechanical systems.

M&R Engineering led the electrical and mechanical design team through schematic design, design development, and construction documents stages.  We also developed construction sequence documents for all the new electrical systems to be installed in concert with the structural elements of the re-construction, as the bridge is re-built in 46 segments from Dartmouth to Halifax.
