Project Update – August 30, 2021
What’s Happening in Traffic This Week
Canada Olympic Drive S.W. Lane Closures
From 7 a.m. to 5 p.m., September 1 to 3, 2021, the right lane will be closed on eastbound Canada Olympic Drive S.W. for streetlight installation.
The right lane on westbound Canada Olympic Drive S.W. will also be closed from 7 a.m. to 5 p.m. for a single day between August 30 and September 3, 2021. This lane closure is needed to accommodate a concrete pour on the north side of the road.
Crestmont Boulevard S.W. Reduced to One Lane
On Wednesday, September 1, from 9 a.m. to 3 p.m., Crestmont Boulevard S.W. will be reduced to one lane of alternating traffic. Flag people will be on site to direct traffic.
101 Street S.W. Reduced to One Lane at Lower Springbank Road
On Tuesday, September 7, 2021, from 9 a.m. to 3 p.m., 101 Street S.W. will operate as a single lane of alternating traffic at the Lower Springbank Road S.W. intersection to accommodate utility work in the area. Flag people will direct traffic.
Upcoming Traffic Shift: Ramp from Westbound Trans-Canada Highway to Old Banff Coach Road S.W.
In the coming weeks, the new ramp from westbound Trans-Canada Highway to Old Banff Coach Road S.W. will open. Drivers will need to exit just west of Valley Ridge Boulevard N.W., which is a distance from the ramp itself. Please watch for directional signage in the area.

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. For all other project information, please visit westringroad.ca.
We appreciate your patience during construction.
July Progress Snapshot
Crews worked almost 40,000 hours in July and reached some major project milestones, including paving the new Crestmont Boulevard S.W. alignment and 1 Avenue S.W. roundabout, and installing girders for the remaining Trans-Canada Highway bridges over Valley Ridge Boulevard N.W.

Geotextile fabric – or filter fabric – lines trenches where subdrains will be installed under the MSE wall
Subdrains use small, perforated pipe in shallow, gravel-filled trenches to collect groundwater and convey it to larger outlet pipes. The permeable pipe allows water in but keeps gravel and debris out.
The subdrains are covered with geotextile fabric once installed
This polypropylene (plastic) geogrid improves the rigidity of the soil – this is known as tensile strength (stays together instead of pulling apart).

Stoney Trail Interchange
Roadwork for the loop ramp from westbound Trans-Canada Highway to southbound Stoney Trail is underway.
