Highway 64 – Clear River Valley

This study focuses on the potential realignment of Highway 64 through the Clear River Valley.

Highway 64 is a major 2-lane, inter-provincial highway and Alberta’s northernmost connection to the British Columbia border. A primary transportation corridor through Clear Hills County, Highway 64 links most of the county’s hamlets, provides access to the Clear River Campground/Rodeo Grounds, the local agricultural and resource sectors.

The existing section of Highway 64 through the Clear River Valley and crossing the river is increasingly at risk of major slides. Alberta Transportation and Economic Corridors has begun a functional planning study anticipated to be complete in spring 2023, to determine if there is a feasible alternative alignment for crossing the Clear River Valley. The following maps show the study location and limits:

A functional planning study is the first step in understanding the needs for any future highway upgrading. Construction of a highway realignment through the Clear River Valley is not on the provincial construction program at this time. The need for further design leading to future construction will be determined based on the outcomes of this study.

CIMA Canada Inc. (CIMA+) will conduct the functional planning study, which will:

  • assess conditions and constraints in the study area
  • identify the concerns and interests of property owners within the study area
  • assess the reliability, stability, safety and costs of potential alignments
  • if a potentially feasible alignment is identified, develop a realignment plan that:
    • provides the most appropriate design given site constraints
    • addresses stability and safety, community interests, environmental, historical resources, drainage and other impacts
    • identifies access management needs
    • identifies land requirements
