Project Update – March 28, 2022
What’s Happening in Traffic This Week
Single Lane of Alternating Traffic on 17 Avenue S.W.
On Tuesday, March 29 and Wednesday, March 30 from 9 a.m. to 3 p.m., 17 Avenue S.W. will be reduced to a single lane of alternating traffic between 101 Street S.W. and Cortina Drive S.W. for utility work.
Eastbound Trans-Canada Highway to Valley Ridge Boulevard N.W. / 109 Street S.W. Ramp Detour
On the morning of Wednesday, March 30, the existing ramp from eastbound Trans-Canada Highway to Valley Ridge Boulevard N.W. / 109 Street S.W. will be closed to allow for construction on the ultimate alignment. Traffic will be detoured to the northbound Stoney Trail exit ramp to access 1 Avenue S.W.
Short Traffic Stoppage at 17 Avenue & 101 Street S.W.
On Wednesday, March 30, there will be a short traffic stoppage at the 17 Avenue and 101 Street S.W. intersection to string electrical cables. The stoppage is expected to last approximately five minutes. Flag people will direct traffic.
All work is weather dependant. Please check 511 Alberta and The City of Calgary’s traffic information map for up-to-date information on traffic detours and speed reductions.
Ground Improvements on Former Valley Ridge Boulevard N.W.
While we all know it can snow in May in Calgary, spring’s arrival does provide some confidence that temperatures will be consistent enough to begin ground improvements on the former Valley Ridge Boulevard N.W.
Crews inspect the subcut or belowground excavation south of the existing Trans-Canada Highway lanes 
The first lift of material is recycled concrete 
A geotextile material called Combigrid is used to stabilize and reinforce the soil

This area will be filled with material to form the road embankment for the new Trans-Canada Highway bridges.
Reinforced Soil Slope Along Former West Valley Road S.W.
Just north of the businesses on West Valley Road S.W., a reinforced soil slope is being constructed for the ramp from eastbound Trans-Canada Highway to Stoney Trail.
Reinforced Soil Slopes (RSS) are compacted embankments that use geosynthetic material to stabilize slopes. RSS are an economical alternative to conventional grade separations (structures) because they use less material, reduce construction time and minimize right-of-way requirements.

17 Avenue S.W. Bridge Deck Hoarding
Hardening concrete is actually a chemical reaction and it requires a specific temperature range (which varies depending on the concrete mix). Curing blankets and hoarding tarps provide insulation to maintain the desired temperatures during cooler months.
White rolls of curing blankets are lined up to cover the fresh concrete bridge deck

The temperature inside the hoarding is measured frequently to ensure it is maintained so the concrete cures as prescribed
