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!
July 2023
We opened the newest twinned section of Highway 104 in July 2023. Hundreds of Nova Scotians worked for many years to make this drive safer, more efficient for business and to better connect our communities. It's truly a made in Nova Scotia success story.
Highway 104 Twinning Project is nearly complete!
The travelling public is now driving on 38 kilometres of twinned highway from Sutherlands River to Antigonish.
