The province has signed a $580 million dollar deal that includes the Mackay Highway being expanded to six lanes.
It also includes the construction of the last 55 kilometres of four-lane highway on Route 1 from Waweig to St. George.
The Department of Transportation says in terms of value, it's the largest highway project in the province's history.
Dexter Developer General Partnership says the project will provide 900 jobs over 4100 months mostly for New Brunswickers.
Premier Shawn Graham, Transportation Minister Denis Landry and Charlotte the Isles MLA Rick Doucet all attended today's announcement.
