The Project, located a few kilometers away from the rural and agricultural community of the Town of Nanton, Alberta, included decommissioning and reclamation of an abandoned rail bridge and line, and realignment and reconstruction of the existing Highway 2 in both directions. Additionally, the Project includes associated intersection improvements, utility improvements, and construction of two minor connector roadways that provide access to the new alignment.

The main purpose of the Project is to improve safety and upgrade design standards in this portion of the corridor, especially for freight traffic. The Highway 2 East Extension Project was in the final stages of construction and approval at the time of rating and was awarded for construction in March 2011.

The east portion of the project alignment encroaches on the Silver Lake wetland area, which was bisected by previous Township Road 170 via culverts and has been previously degraded due to nearby agricultural and oil and gas drilling in the area. The project included a wetland impact minimization and mitigation approach, environmental management plan during construction, and also environmental monitoring during construction works.


  • Materials management approach resulting in balanced earthwork, pavement and rail ballast reclamation on site, and locally sourced materials.
  • One of first projects to earn Custom Credit points for Freight Access, before it was officially a credit
  • ECO Plan provided with the project included provisions for management of an agricultural pest, clubroot, which is a crop disease that can be spread during construction
