Technical engineering and environmental studies have and will continue to be undertaken to support to development of the project.

Work includes:

  • Geotechnical investigations to determine the depth, type and consistency of the soils under the proposed interchange
  • Updated traffic counts to confirm previous counts and assist in designing the interchange and connections
  • Noise monitoring adjacent to the Trans-Canada Highway to assist in developing noise mitigation options
  • Environmental work to identify potentially sensitive ecosystems and species at risk, and to determine specific mitigation strategies
  • Archeological fieldwork, working with First Nations, to identify any possible archaeological sites
  • Ground surveys to confirm the existing topography

Reports available:

McKenzie Interchange Ecosystem Mitigation Plan
Part 1: Ecosystem Valuation (July 2017)

This is the first of multiple reports which will address mitigation of the project impacts to natural vegetation. This report provides provisional valuations for the Garry Oak woodland north of the highway and the Trembling Aspen forest south of the highway, in Cuthbert Holmes Municipal Park. Subsequent reports will identify options for off-site mitigation of the impacts, provide cost-estimates for the most efficient and economical options, and provide detailed project plans for the preferred options, once selected.

Environmental Noise Impact Assessment (May 2016)

This report documents existing noise exposure levels predicted at noise-sensitive land uses near the project, the future noise climate predicted 10 years after completion of the project, noise impact assessment results and potential noise mitigation options.

Traffic Analysis Final Report (May 2016)

This report addresses existing traffic conditions, evaluates the interchange options and predicts future traffic volumes and travel times.

Baseline Noise Monitoring and Assessment (January 15, 2016)

This report summarizes the baseline monitoring results and baseline noise predictions in proximity of the future interchange. The project team continues technical work and discussions with key stakeholders regarding noise mitigation plans.

The Ministry’s current noise policy is available online.

Environmental Assessment Report (April 5, 2016)

This report identifies environmentally sensitive features in and around the project footprint*, determines potential impacts, possible mitigation, and regulatory compliance requirements.

*Note – the environmental assessment was based on the largest proposed project footprint, therefore the partial cloverleaf option is used as the example to cover all the proposed conceptual design options
