Construction: Past, present and future
Starting in 1981, 83 km of the Trans-Canada Highway (TCH) in Banff National Park were upgraded and mitigated, in phases, from two lanes to a four lane divided highway. TCH twinning project in Banff National Park addressed three ecological and transportation goals:
- Improve motorist safety
- Reduce highway-related wildlife mortality and habitat fragmentation
- Improve the flow of goods and services on Canada’s national highway.
