The award-winning projects below are a testament to the calibre of the engineering performed at Harbourside.
Lower Don Bridge and Don Valley Parkway
Harbourside Engineering is acting as the specialist bridge erection engineer for the Don Valley Parkway Bridge. In addition, Harbourside was also responsible for the Lower Don Enabling Works, and quality verification engineering (both structural and geotechnical).
Etobicoke Creek Rail Bridge Replacement
Harbourside Engineering was retained by Demathieu & Bard Construction to design a versatile, modular gantry system to replace the 122‑year‑old Etobicoke rail bridge for Metrolinx, which aimed to modernize a critical commuter corridor. The gantry enabled the safe removal and installation of bridge spans during three short (51‑hour) weekend closures. This innovative approach reduced disruptions and avoided the environmental impacts of traditional crane-based methods, delivering significant benefits for commuters of the busy Lakeshore West Line.
Old Champlain Bridge Deconstruction
Harbourside Engineering was named as Deconstruction Engineers for the Old Champlain Bridge, which joined Brossard to Montréal, Québec, and spanned the active St. Lawrence Seaway Navigation Channel as the busiest vehicular bridge in Canada. Reports indicated hazards related to the structure of the bridge, with partial or complete collapse being a legitimate risk. Its demolition ensured the safety of Québec residents, and Harbourside was awarded the 2023 Lieutenant Governor’s Award for Excellence in Engineering as a result of this project.
Highway 104 Twinning (Part 3)
The Highway 104 Twinning Project was a Design, Build, Finance, Operate, and Maintain (DBFOM) project, including twinning the 100 series highway between Sutherlands River and Antigonish, Nova Scotia, with new interchanges and bridges. Working as part of the Dexter Nova Alliance (DNA), Harbourside Engineering Group completed the design of bridge structures, and was awarded the 2025 Lieutenant Governor's Award for Excellence in Engineering for this project.
Rocky Barachois Bridge Replacement Approach
Gros Morne, Newfoundland, continued its series of bridge replacement projects with a focus on the Rocky Barachois Bridge in 2016. Harbourside was contracted to provide detailed concept, design, and tender documents. Harbourside Transportation Consultants completed the design of the vertical and horizontal alignments, while Harbourside Geotechnical Consultants investigated the approaches at this site. The design of the new bridge was undertaken by Harbourside Engineering Consultants, making this project a truly comprehensive endeavour for the group.
THE BIG LIFT: Angus L. MacDonald Redecking Project
The existing deck and stiffening truss of the Angus L. Macdonald (ALM) Bridge, spanning over the Halifax Harbour in Nova Scotia, were nearing the end of their service life and needed replacement. The project consisted of the design of the new suspended deck and stiffening truss, as well as the analysis of the bridge during erection and the design of the main erection equipment. Harbourside received the Lieutenant Governor’s Award for Excellence in Engineering in 2018 for its work on The Big Lift.
Central Avenue – Accelerated Bridge Construction
The Central Avenue replacement bridge in Fort Erie, Ontario, was designed use the same footprint as the existing bridge. Harbourside was engaged to provide the structural design of four self-stabilizing temporary steel bents which were supported on spread reinforced concrete footings founded on bedrock. With 11,300 vehicles crossing the centrally located bridge daily, it was important to ensure traffic disruptions were kept to a minimum. The completed bridge features two traffic lanes, two bike lanes, and sidewalks.
Seal Island Bridge Emergency Repair
The Seal Island Bridge Structure, or the Great Bras d’Or Crossing, in Victoria County, Nova Scotia, is the third largest bridge span in the province and a crucial link in the Trans-Canada Highway between Sydney and Baddeck. The NS Department of Transportation and Infrastructure Renewal consulted Harbourside to provide structural engineering services for the assessment of the three span continuous main span and rehabilitation of a damaged truss diagonal. Harbourside developed an innovative structural repair with detailed phasing drawings.
Bonnie Road Bridge Emergency Collision Repairs
Harbourside Engineering Consultants was sourced by the NS Department of Transportation and Infrastructure Renewal to provide emergency repair services after four girders were struck by a vehicle on the Bonnie Road Underpass Bridge that spans over Highway 101 in Meteghan, Nova Scotia. Harbourside’s scope of work included determining the extent of repairs, demolition design and phasing, detailed design of new bridge components, and erection phasing. Although a detour was necessary during the bridge's closure, it was vastly reduced due to Harbourside's approach.
Truro Heights Pedestrian Bridge
The Truro Heights Pedestrian Bridge was planned for construction in 2015 beside the overpass at Exit 13, spanning over Highway 102 and forming a vital part of the new pedestrian trail linking Truro Heights to the recently constructed Rath Eastlink Community Center in Nova Scotia. Harbourside Engineering Consultants provided the structural bridge design services for this project, as well as site inspection services during construction. Harbourside also developed the innovative girder erection method which mitigated the disruptions to the Highway 102.
Warren Brook Bridge Replacement
A call for proposals was issued in 2015 for the design of a replacement for the Warren Brook Bridge, spanning over the Warren Brook along the Cabot Trail near Ingonish Beach, Nova Scotia. After a preliminary design stage that evaluated several structure types and highway alignment options, Harbourside determined the optimal solution. The project objective was to remove and replace the existing bridge in an efficient, cost-effective and environmentally friendly manner, and to realign the approaches on each side of the bridge to meet current standards.
Highway 104 Twinning (Part 2)
As a part of a major initiative by the NS Department of Transportation and Infrastructure Renewal to twin Highway 104 through the town of Antigonish, Nova Scotia, Harbourside Engineering Consultants received the contract to design six major structures along the new alignment. Harbourside provided preliminary designs of various options for each structure and final designs with tender-ready documents. This monumental task was undertaken by various groups, working in conjunction as the Dexter Nova Alliance.
Highway 104 Twinning (Part 1)
The twinning of Highway 104 comprised of various projects for the roadway's modernization, as twinned highways are safer and more efficient than their single-lane counterparts. Harbourside Engineering Consultants completed the design of the twin overpass structures at the Trunk 7 intersection near St. Francis Xavier University, through Antigonish, Nova Scotia, and received the 2025 Lieutenant Governor’s Award for Excellence in Engineering resulting from work on this project.
