M1 Westlink is a long-term concession to design, upgrade, finance and operate the M1 Westlink road in Belfast, UK. The project commenced in April 2006 and required a significant amount of construction work to upgrade key sections of the existing road network. This consisted of approximately 60 km of motorway and a short section of linking dual carriageway through the heart of Belfast. The project was complete approximately six months ahead of schedule in November 2009. The concession expires in 2036 and is availability-based with no volume risk.
This project was the first road project in Northern Ireland to be procured using the Design, Build, Finance and Operate form of Public Private Partnership.
