Girders Installed March 2021
Looking south at the 54m long girders installed on both the north and south spans of the bridge with the Paskapoo slope in the background.
Bridge Deck Poured December 2020
Tarps cover the recently poured concrete bridge deck to maintain moisture and temperature.
Girders Lifted January 2021
Looking east at the north and south spans over the Trans-Canada Highway.
Bridge Deck Construction April 2021
Looking north at bridge deck rebar and concrete on the four mainline Stoney Trail bridges.
Open to Traffic November 2020
Opening this basketweave bridge was a major milestone.
Abutment and Mechanically Stabilized Earth Wall Construction April 2021
Looking north at the caisson foundation and concrete panels for the mechanically stabilized earth (MSE) wall being constructed for the west abutment.
New Bridges Open to Traffic December 2020
Looking west, a bird's-eye view of the Trans-Canada Highway detour over the new bridges at Valley Ridge Boulevard N.W.
Girders Installed January 2021
One of only four bridges on the project supported by steel girders, each girder is over 60 metres long and longer than the Leaning Tower of Pisa!
South Span Girders Lifted March 2021
Looking north at the south-span girders installed over the eastbound Trans-Canada Highway lanes.
Constructing the Bridge Deck December 2020
Looking west at the diaphragm rebar assembly. The diaphragm rebar will be filled with concrete, tying in the girder ends over the centre pier.
Earthworks November 2020
Looking west, the completed reinforced soil slope is visible on the left.
Deck Formwork Assembly April 2021
With the girders in place and overhang brackets installed, work is underway on the deck formwork.
Girders Lifted February 2021
Looking east, all four girders, each approximately 36 metres long, have been successfully installed.
Soil Nail Wall Completed December 2020
The soil nail wall will stabilize the steep slope along the re-aligned Crestmont Boulevard S.W.
Stormpond Constructed September 2020
Construction on this stormpond is complete.
Deck Poured April 2021
With the formwork complete, the concrete bridge deck has been poured.
Slope Completion November 2020
Looking southwest, the completed reinforced soil slope covered with hydroseed. Reinforced slopes are cost-effective alternatives to concrete walls that use compacted geosynthetic material to stabilize steep embankments.
Stormpond Construction Complete April 2021
Looking northwest, this pond is now in use.
Controlled Blasting Milestone May 2021
A major milestone has been reached with the conclusion of daily controlled blasts on the Paskapoo slope. Localized, intermittent blasting will be still be required for the two stormline trenches on either side of Stoney Trail.
Trans-Canada Highway Grading
145,000 cubic metres of fill will raise the Trans-Canada Highway about 7m in this area.
Trans-Canada Highway / Stoney Trail interchange
These are the heaviest girders transported in Alberta, traveling through a valley near Hanna. They had to travel to a specific bridge to cross the Red Deer River that could handle its weight.
