Nova Scotia Highway104

About the Project

Highway 104 is a major transportation link in Nova Scotia, connecting the province to New Brunswick and the mainland to Cape Breton Island.

Dexter Nova Alliance (DNA) is the consortium selected by the Nova Scotia Department of Transportation and Infrastructure Renewal (NSTIR) to Design, Build, Finance, Operate, and Maintain (DBFOM) the new stretch of highway. In addition, DNA will be responsible for the operation and maintenance of an additional 25 kilometres of existing highway over a 22-year period.

Project Progress


This week, we reached substantial completion for the HWY 104 Twinning Project, making the highway safer and more efficient for the travelling public.

Through continued collaboration between our province, our people, and our local businesses, we will see Nova Scotia continue to grow and prosper.

Thank you to our workers, our suppliers, and everyone involved!
