Project Update – October 12, 2020
What’s Happening in Traffic This Week
Trans-Canada Highway reduced to one lane – Prepare to keep right on the Trans-Canada Highway for the remainder of October. Inside lanes will be closed in three separate locations to pave medians for future detours.
All work is weather dependent. Please check 511 Alberta and The City of Calgary’s traffic information map for up-to-date information on traffic detours and speed reductions.
We appreciate your patience during construction.

Reinforced Soil Slopes Complete
The two Reinforced Soil Slopes (RSS) supporting the ramp from northbound Stoney Trail to eastbound Trans-Canada Highway are done. RSS are compacted embankments using geosynthetic material to stabilize slopes. They are a cost-effective alternative to concrete retaining walls and are often used in constrained areas like the one shown below.
For a look back at this area at the start of RSS construction, check out the August 17, 2020 update.
