What’s Happening in Traffic

Traffic Shift to New Bow River Bridge

This week, southbound Stoney Trail traffic will be shifted onto the new Bow River bridge. Brief, intermittent closures will be required to reroute traffic onto the new road and speed limits through the area will be reduced to 60 km/hr. The shift will happen overnight to minimize traffic disruptions.

In the coming weeks, northbound traffic will also be shifted to accommodate rehabilitation on the existing bridge.

Please watch for signage for information about the closures and adjusted traffic patterns.

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.

Stoney Trail Construction

Hundreds of skilled tradespeople are working on the South project site each day.

Looking north at paving on the southbound lanes
Machines spreading fill for the northbound lanes north of 17 Avenue S.W.; in the background, paving on the southbound lanes is visible
South of 17 Avenue S.W. a large, heavy truck is used to ‘proof roll’ the subgrade; proof rolling is a way of testing the subgrade compaction to make sure there are no areas giving way under the weight of the vehicle
Looking south at machines spreading and compacting material for Stoney Trail near 17 Avenue S.W.; water is sprayed on loose material to reduce dust
Testing the subgrade density on the northbound lanes, north of the Highway 8 interchange
Compacted Granular Base Course (GBC) for the northbound Stoney Trail lanes approaching the flyover; GBC the foundation layer of the pavement structure. It provides drainage and protects the pavement from frost.

Bow Trail S.W. Interchange

The Bow Trail S.W. interchange is rapidly taking shape.
