Trans-Canada Highway Twinning Project, Phase IIIB: November 2005
Version (PDF, 324 Kb)
With trees cleared for the second lane, twinning of the Trans-Canada Highway
(TCH) is proceeding on a section of highway east of Lake Louise. Over the
last few months, the challenge for the project team has been to stay within
its budget and general project schedule in the face of rising construction
costs and the in-demand labour market. Despite the challenge, Parks Canada
remains committed to twinning as much highway with associated mitigations
that current funds will permit, thus delivering the world-class project described
in our environmental assessment. When completed, the section twinned will
contribute to safer travel conditions for people and wildlife, and smoother
flow of goods and services on Canada’s national highway.

- Contracts for initial project work were tendered as scheduled this summer.
However, construction costs have been increasing and tenders came in well
above estimates. This resulted in some delays as the tenders had to be repackaged
and again posted for bid.
- Preparation for the new lanes is underway with special measures in place
to protect soils, water quality, and native plant and wildlife communities.
- Initial grading work began in mid-October and will continue, Monday through
Saturday, until mid-December. Blast rock is going into place on the north
side of the TCH from the Bow River to the start of twinning at Lake Louise.
Blasting and rock removal is underway about 3 km east of the Lake Louise
junction, requiring traffic delays of up to 45 minutes between 10 am - 2
pm. For long weekends and the Men’s and Women’s World Cup Downhill
and Super-G weekends at the Lake Louise Ski Area, construction will cease
at noon on Friday and resume on Monday. Work will resume in spring 2006
with placing of fill around the Moraine Creek bridge area.
- A separate gravel crushing operation for construction aggregate is underway
with work expected to finish in mid-December. It will not affect traffic.
- Please obey posted speed limits and flag people through the construction
- The next Stakeholder Advisory Committee meeting is anticipated for sometime
in February to review the past year and provide a complete project update.

Project Quick Facts
- $50 million budget through Infrastructure Canada to start project. Overall
cost to twin from Castle Junction to the Alberta-BC border is estimated
at $200 million.
- Summer traffic volumes on the TCH in the park average one vehicle every
six seconds. Traffic volume is currently increasing two percent annually.
- 48 km of the TCH’s 83 kilometres in Banff National Park was twinned
between 1979 and 1997.
- Since 1996, monitoring has revealed that 10 species of large mammals have
used the existing 24 wildlife crossing structures more than 60,000 times.
- Eighteen major crossing structures and dozens of smaller ones are planned
for the section of highway between Castle Junction and the Alberta-BC border.
