Trans-Canada Highway Twinning Project
Phase IIIB: May 2006
Version (PDF, 264 Kb)
The highway twinning project east of Lake Louise moved ahead on a number
of fronts this past winter. Clearing for the new second lane has occurred
from east of Lake Louise to 3 km east of Moraine Creek, a distance of 10 km.
The Canadian Pacific Railway overpass, wildlife underpass near the overflow
campground, and the Bow River and Moraine Creek bridge areas have also been
busy with work to prepare new foundations.
However, the project has not escaped the impact of rising construction
costs and the in-demand labour market. The current 50 million dollar budget
has been intensively managed to build as much of the original project as possible.
But the distance that can be twinned has been decreased 4 km. This deferred
4 km section, along with its associated wildlife fencing and crossing structures,
will be built should further funds become available. The commitment to deliver
the entire world-class project described in the environmental assessment remains

- Twinning will extend from just east of Lake Louise to the west side of
the Mt. Temple Viewpoint – a distance of 6 km. Clearing for the second
lane has been completed 4 km east of this point as part of the original
project plan but it won’t be twinned under the current budget. Material
removed from the large earth cut by Lake Louise will be deposited as road
bed along this section (from Temple Viewpoint to Moraine Creek) as originally
- Though the twinning will now end short of Moraine Creek, the new 25 m
wide Moraine Creek bridge will be completed. The design of the new bridge
and one of the wildlife underpasses is the same, which brought cost savings.
Completing the bridge now ensures further twinning can occur quickly should
funds become available.
- All wildlife crossings planned for the section being twinned under the
available funding will be built. Highway fencing will still extend west
of the twinned section to end on the west side of Lake Louise as originally
planned. This fenced section will have a wildlife overpass west of Harry’s
Hill and an underpass at the fence end.
- A pedestrian pathway will be built as part of the new Canadian Pacific
Railway overpass east of Lake Louise. A second pedestrian crossing, associated
with Harry’s Hill residential area, will be built when further funding
- The design work for the wildlife overpass west of Lake Louise, and the
highway fencing plus Texas gates will be completed and go to tender this
- The design of the wildlife overpass east of Temple Viewpoint will be completed,
but won’t go to tender at this stage.

TCH construction schedule
Roadwork is underway 24 hours per day, seven days per week from April until
the end of July. Expect intermittent five-minute delays around the clock, as
well as possible delays of up to 30 minutes between 9 a.m. and 4 p.m. Construction
will shut down over long weekends.
Park Visitor Notes
- Construction work has been arranged to ensure the Bow River boat put-in
east of Lake Louise remains accessible this season.
- The Lake Louise Overflow Campground, which is within the construction
area, will be open this summer. Campers will be encouraged to use campgrounds
along the Icefields and Bow Valley Parkways once the Lake Louise Campground
is full. But the Overflow remains available as a camping option.
- The Whyte Museum in Banff is hosting an intriguing exhibit featuring remarkable
wildlife images and video clips. The exhibit visually shows results from
10 years of monitoring of the 24 existing highway wildlife crossings. It’s
in place until October 9.
