Province, Dexter Nova Alliance Break Ground on Highway 104 Twinning Project

Construction has begun for the twinning of the Highway 104 between Sutherlands River, Pictou Co. and Antigonish.

Crews and machinery broke ground today, July 17. The $718 million project will make the highway safer for motorists and improve the efficiency of one the province’s most important transportation corridors.

“This project will save lives and provide travellers and business with a high-quality highway for many years to come,” said Lloyd Hines, Minister of Transportation and Infrastructure Renewal. “A safe and efficient highway system is essential to the economic and social well-being of Nova Scotia. Our partnership with Dexter Nova Alliance will deliver on that goal.”

Dexter Nova Alliance, led by local contractors Dexter Construction and Nova Construction, with BBGI as an equity partner, was awarded the contract to design, build, finance, operate and maintain a section of Highway 104 in May.

Construction will be completed before the end of 2023.

The Highway 104 project, part of the Trans-Canada Highway, consists of construction of a twinned highway beginning east of New Glasgow near Exit 27 at Sutherlands River, and running east to just west of Exit 31.

The project includes 28 kilometres of new two-lane twinned highway and 10 kilometres of new four-lane twinned highway. There are two new interchanges and about 24 new bridges. Dexter Nova Alliance will also upgrade the existing section of highway.

The federal government is contributing $90 million to the project under the National Trade Corridors Fund.


This is a significant project that will have a positive impact on our province for decades to come. It will be built by Nova Scotia-based companies for Nova Scotians and we are proud of that. We are looking forward to getting started and seeing this long anticipated work to completion. Ken MacLean, vice-president, Dexter Nova Alliance

Today we take a very important step towards safer highways in Nova Scotia. After many lives lost and changed forever, we are moving towards safer roads between Sutherlands River and Antigonish. I thank everyone for your support and seeing one of my dreams come true. Joe MacDonald, chief of Barneys River Volunteer Fire Department

“I am very encouraged to see the twinning of Highway 104 moving forward. This important project will create hundreds of good paying jobs and will foster long-term prosperity in our communities. Most importantly, upgrading this highway will save lives by significantly improving the safety of one of our region’s most dangerous stretches of highway."

Sean Fraser, Member of Parliament, Central Nova, on behalf of Transport Canada Minister Marc Garneau
