Nova Scotia’s Highway 104 Twinning Project Reaches Substantial Completion

WSP leads the design for the roadway’s expansion.

The $364.3-million twinning of Highway 104 from Sutherlands River to Antigonish has reached substantial completion, providing motorists with a safer drive on one of the province’s most critical roadways.

The project, built for Nova Scotians, by Nova Scotians, significantly improves the highway network in the Cape Breton to the New Brunswick border corridor. The upgrade includes 10 kilometers of new four-lane and 28 kilometers of twinned highway, two new interchanges, 24 new bridges, and a number of environmental improvements including wildlife corridors and fencing. It was delivered using the public-private partnership (P3) DBFOM model by Dexter Nova Alliance (DNA), who will also be responsible for the operations and maintenance of the highway for the next 20 years.

As the Lead Design Engineer for DNA, our team was able to provide the detailed design for most aspects of the Highway 104 Twinning Project. Utilizing a local team in Nova Scotia, one that understood the needs of the motorists using the highway corridor and how it would impact the surrounding environment, helped us provide smart, innovative solutions for the project’s design.”

The project, which began construction in May 2020, was successfully delivered thanks to the collaborative work of the project team. Utilizing the P3 model for project procurement, the team was able to utilize its collective local expertise and understanding of the local environment to minimize project risk. The result was the delivery of a transportation corridor that will provide greater access to residents and visitors for decades to come.

“It truly was a team effort that allowed us to deliver the Highway 104 project successfully,” said Quesnel. “Our partners in DNA helped us deliver a project that our team, and Nova Scotians, should be proud of.”
