The Canadian Council for Public-Private Partnerships Announces Highway 104 Twinning Project for 2020 National Awards for Innovation and Excellence in P3s

Highway 104 Sutherlands River to Antigonish Twinning Project wins Project Development Silver Award

The twinning of this stretch of Nova Scotian highway, from the boundary with New Brunswick to Antigonish, has been a significant community concern for years to help reduce fatal collisions. It is also the first highway P3 project in the province in more than 20 years and was one of the first P3 projects to reach financial close last spring in the midst of highly volatile financial market conditions caused by the pandemic. Among other things, the awards committee noted that considerable cooperation and flexibility were required by all parties including government, bank lenders and bond underwriters/purchasers to close the project —— and with no impact on overall project duration.
