Project Update – September 6, 2021
What’s Happening in Traffic This Week
Crestmont Boulevard S.W. Single Lane Alternating Traffic
Beginning tomorrow (September 7), and lasting approximately one month, Crestmont Boulevard S.W. will be reduced to a single lane of alternating traffic to build the connection between the existing road and the new Crestmont Boulevard S.W. alignment.
Exit Shifted: Eastbound Trans-Canada Highway to Valley Ridge Boulevard N.W. / Crestmont Boulevard S.W.
Tomorrow night, September 7, the exit from eastbound Trans-Canada Highway to Valley Ridge Boulevard N.W. and Crestmont Boulevard S.W. will be shifted east of (after) the existing exit. Please be patient as drivers adjust to the new location.

101 Street S.W. Reduced to One Lane at Lower Springbank Road
Tomorrow (September 7) 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 intersection. This lane closure is needed for utility work in the area. Flag people will direct traffic.
Reminder: Red Means Stop
A recent safety audit on the South project confirmed that many drivers are failing to stop at red lights for construction crossings. The Calgary Police Service is monitoring the area. The penalty for running a red light is a fine up to $388 and three demerit points. Please drive carefully through the construction zone and obey traffic laws.
September 17: Highway 8 & 101 Street S.W. Permanently Closed
On Friday, September 17, the intersection at Highway 8 and 101 Street S.W. will permanently close. Emergency service response times will not be impacted.

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.

Last Pile Driving for the North Project
Not too long ago we were celebrating ‘firsts’, and now the milestones are shifting to ‘lasts’. The first of the ‘last’ milestones to mark: piling for the last bridge on the North project is nearing completion.
Looking south at the site for the northbound Stoney Trail bridge
A steel frame to guide the abutment piles sits on top of casings (sleeves) 
The piles are driven into the casings, which will be filled with gravel or insulation, allowing the pile to move as it absorbs force from the bridge

Bridge Deck Pour #15
The now familiar yellow truss screed is set up on the northbound to westbound directional ramp on the Trans-Canada Highway / Stoney Trail interchange, signalling preparations for the fifteenth bridge deck pour on the North project.
This bridge is 40 feet tall and spans more than 100 metres from end to end, which is too long to pour the deck at one time. Instead, ~418 cubic metres of concrete will be poured in two stages.

Old Banff Coach Road Exit Shifted
The exit from westbound Trans-Canada Highway to Old Banff Coach Road is now just west of Valley Ridge Boulevard N.W.; drivers need to exit much sooner than before. Please watch for directional signage in the area and be patient while everyone adjusts to the new exit location.

Old Banff Coach Road S.W.
All 26 girders have been installed on the Old Banff Coach Road S.W. bridge over Stoney Trail. Thank you for your patience with the intermittent traffic stoppages for girder deliveries during the month of August.
One of the final girders is lifted into place on the west span
Each girder end rests on a bank pad, which consist of a concrete plinth (a load bearing base) and a rubber bearing pad to accommodate expansion and contraction.

Bow Trail S.W. Interchange
Bridge Construction
The excavation for the shallow foundation has been backfilled and compacted except the areas immediately surrounding the pier columns 
Structural backfill – soil with no rocks or organics – is highly compactible and placed around the centre pier columns for greater soil stability
