Project Update – July 12, 2021
What’s Happening in Traffic This Week
Nightly Ramp Closure: Eastbound Trans-Canada Highway to Northbound Stoney Trail
Each night until July 22, between 10 p.m. and 5 a.m., the ramp from eastbound Trans-Canada Highway to northbound Stoney Trail will be closed for bridge work. Traffic will be detoured to the Bowfort Road N.W. interchange.
Overnight Lane Closure on Westbound Trans-Canada Highway
Tonight (Monday, July 12) and tomorrow night (Tuesday, July 13), westbound Trans-Canada Highway will be reduced to one lane west of Valley Ridge Boulevard N.W., between 9 p.m. and 5 a.m., for work in the ditch.
EXTENDED: Lower Springbank Road S.W. Single Lane of Alternating Traffic
ENMAX work along Lower Springbank Road S.W. will continue until July 14. A single lane of alternating traffic will be in place adjacent to the areas where they are working.
Township Road 242 Closure
Starting Thursday, July 15, Township Road 242 will be closed between Lower Springbank Road S.W. and 101 Street S.W. for 17 Avenue S.W. interchange construction. Traffic will be detoured onto Lower Springbank Road S.W. and 101 Street S.W. This is the first of several detours that will be implemented in this area over the coming months. This portion of Township Road 242 will remain closed until this fall (2021).
While efforts will be made to minimize traffic delays as much as possible, there is significant work to be completed. Traffic delays should be anticipated. Please plan accordingly.
Traffic Shift for Valley Ridge Boulevard N.W. / Crestmont Boulevard N.W. to Eastbound Trans-Canada Highway
In the coming weeks, traffic from Valley Ridge Boulevard N.W. / Crestmont Boulevard S.W. going east on the Trans-Canada Highway will be shifted to a new detour on the re-aligned West Valley Road S.W. Access to businesses along West Valley Road S.W. will also be shifted to the south side using the new road alignment.
No other traffic movements will change. Access from westbound Trans-Canada Highway to Valley Ridge and Crestmont remains the same, as does the access from eastbound Trans-Canada Highway to northbound Stoney Trail.
Please watch for detour signage, drive cautiously and be courteous to other drivers. These roads are brand new and unfamiliar; it will take some time for drivers to adjust to the new route.
The new detour will include the new roundabout at 101 Street S.W. For a refresher on how to use a roundabout, check out the June 1, 2020 newsletter.
Old Banff Coach Road S.W. Construction Crossing
The signalized construction crossing on Old Banff Coach Road S.W., between 89 Street S.W. and 101 Street S.W., will now be controlled by flaggers. The crossing is expected to be in use until the end of August.
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.

Traffic Tie-ups Last Week
Travel through the North project area was slow and congested last week as a result of some uncontrollable events. The heavy rain caused flooding and debris that required lane closures on the Trans-Canada Highway in both directions and on Valley Ridge Boulevard N.W. to clean out stormwater facilities and stabilize slopes. Then the ramp to eastbound Trans-Canada Highway had to be modified to fix equipment under the road causing a power outage.
Thank you for your patience while the issues were resolved.
Valley Ridge Boulevard N.W. Interchange
Major progress is happening on the Valley Ridge Boulevard N.W. interchange. After weeks of Mechanically Stabilized Earth (MSE) wall construction, the abutment forms have been installed, concrete poured, and girders placed on one of the two bridges.

1 Avenue / West Valley Road / 101 Street S.W. Roundabout
The roundabout at 1 Avenue / West Valley Road / 101 Street S.W. is substantially complete and will form part of a new detour for traffic from Valley Ridge and Crestmont wanting to head east on the Trans-Canada Highway.

Stockpile Adjacent to The Slopes
Beginning this week, topsoil will be stockpiled within the Transportation Utility Corridor (TUC) at the south end of the Slopes. While topsoil is being stockpiled, adjacent residents will see construction equipment working close to homes bordering the TUC.
Over the course of the project, numerous semi-permanent stockpiles will be created within the TUC. There is no limit to the height or length of the stockpiles, provided they meet slope stability requirements.

Springbank Ravine Drainage Culvert Installation
After months of work excavating the native material in the ravine and then replacing it with suitable subgrade material, culvert installation is underway. This culvert will allow water to move freely along its natural drainage course under Stoney Trail.

17 Avenue S.W. Work Starting at 5 a.m.
On Thursday, July 15, the concrete pour for the centre piers on the 17 Avenue S.W. interchange will begin at 5 a.m. High temperatures are expected to continue this week and the early start will allow crews to avoid the hottest part of the day, as well as maintain the quality of the concrete, which must stay within a specific temperature range.
The work will involve a concrete pump and generator, which will create some noise. Directional lighting will also be required but will be aimed away from residences as much as possible.
Earthworks, Drainage and Utilities on Bow Trail S.W.
Part of Bow Trail S.W. interchange construction includes underground utility work and grading to extend the road west of 85 Street S.W. and connect to Stoney Trail. Plans for the area include a drainage culvert and a pathway underpass.

Pile Driving Tests at Highway 8
Pile driving tests for the future Highway 8 / Stoney Trail interchange are anticipated to start this week and continue for approximately two weeks (end of July 2021). This work is weather dependent and estimated dates may change.
Pile driving involves a pneumatic (air) hammer striking steel piles, which creates a repetitive pinging or hammering sound. Adjacent residents can expect increased noise and some minor vibrations that will cease once piling is completed.
Impaired Driving
With Alberta officially open for summer and the Stampede underway this week, a reminder that the majority of impaired driving crashes happen on summer nights. Between 2014 and 2018, over half (51.8%) of impaired driving casualty collisions happened between 7 p.m. and 3 a.m.
From 2014 to 2018, on average, each year 47 people were killed and 643 people were injured in collisions involving impaired driving
Impaired driving is preventable when drivers choose to plan for a safe ride home.
