Collector-Distributor Ramp Lanes between Crowchild Trail and Scenic Acres Link N.W.
This week crews continued working on protecting exposed surfaces from erosion within the west ditch of the new Collector-Distributor (CD) ramp lanes. Cover is the single most effective erosion control practice and, in this case, includes placing topsoil in conjunction with seeding.

Despite challenges with changing ground conditions, heavy rain, managing social distancing and COVID protocols, working in live traffic and managing traffic detours, EllisDon and its subcontractors put in 46,459 work hours in May. That’s the equivalent of 62.5 work hours every hour of every day for the entire month!
Refresher on Bridge Elements
With 20 bridges being constructed as part of the North project, many of our updates include information and images of bridges at various stages of construction. Here’s a diagram to help identify the different components of a bridge.
Intersection at Valley Ridge Drive and Valley Ridge Boulevard N.w.
Last year, EllisDon communicated a potential plan to replace the four-way stop at Valley Ridge Drive and Valley Ridge Boulevard NW with a roundabout, as part of the detouring for interchange construction. Since then, design has progressed and it has been determined that construction can be contained within the Transportation Utility Corridor (TUC), making it unnecessary to convert the intersection into a roundabout. Retaining the four-way stop will minimize further construction impacts on the area.
Trans-Canada Highway Reduced to One Lane Overnight for Girder Installations

Geogrid is a geosynthetic material that improves ground stability. Geogrids help reinforce the soil, which pulls apart under tension.
A Reinforced Steepened Slope (RSS) wall is often used to provide grade separation on steep slopes. Steep slopes are classified as structures greater than 70 degrees.
