Project Update – November 15, 2021
What’s Happening in Traffic This Week
Crestmont Boulevard S.W. Open
Both lanes on Crestmont Boulevard S.W. are now open. Thank you for your patience while the final stretch of new road was constructed and utilities were installed.
Guardrail is typically one of the last things installed because its height and proximity to traffic are dependent on the edge of asphalt and the finished grade
Short Traffic Stoppage on Old Banff Coach Road S.W.
On Thursday, November 18, 2021, traffic on Old Banff Coach Road S.W. will be stopped for approximately five minutes between 10 a.m. and 11 a.m. to string an electrical cable across the road.
Old Banff Coach Road S.W. Lanes Re-Opening
Storm line installation on the north side of Old Banff Coach Road S.W. is complete. This week the westbound carriageway is expected to re-open.
Paving the westbound carriageway over the newly installed storm line
REMINDER: Temporary Construction Crossing on Highway 8
This week trucks will be hauling some of the 2,000 cubic metres of fill needed for the eastbound lanes across the highway. The signalized crossing will be controlled by on-site personnel and will only be activated when a construction vehicle is present.
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.
Cantilever Over the River
A cantilever is a structural beam extending from a single support. All summer the pier segments have been cast-in-place, slowly extending out from the bridge piers on the north side of the river. Now they are stretching over the river to connect to the piers on the other side.
The pier segments stretch across the river anchored only on one side, forming a cantilever 
The Bow River bridge is being constructed using box girders – seen in this photo – rather than the more common steel or pre-cast concrete girders used on the other West Calgary Ring Road bridges

Second to Last Bridge Girders Installed
Another milestone on the North project as the third construction season slows for winter – girders have been installed on the second to last bridge.
Pre-cast concrete girders arrive by truck

All seven girders installed
Springbank Ravine
More than 3.5 million cubic metres of fill will be used in the ravine. A cubic metre is roughly equivalent to 1,000 litres, which converts to more than 3 billion litres.

Settlement plates have been installed in the ravine to measure settlement as more fill is added and compacted. This information is used to determine when the soil is stable enough (has enough shear strength) to support the infrastructure being constructed on it.

The white PVC pipe is a protective cover for the reference pipe 
The fill around the settlement plate is compacted and the density is regularly measured to monitor settlement
Highway 8 Interchange
Excavation and shoring wall construction continue just north of Highway 8.
Looking southwest at the interchange site; shoring wall construction is visible in the background 
These steel rods and beams, called tie-backs, hold the temporary wall in place
