What’s Happening in Traffic

Temporary traffic signals at Old Banff Coach Road and 101 Street S.W.

Beginning the week of May 8, 2023, and lasting approximately two weeks, temporary traffic signals will be installed at the Old Banff Coach Road and 101 Street S.W. intersection. Work on the east side of the intersection, including paving tie-ins and curb and gutter work, requires 101 Street S.W. to operate on a single lane of alternating traffic.

Please expect delays.

Street sweeping

Spring cleaning isn’t just for basements and garages; it’s also required on our roadways to clear away gravel from the winter months and mud tracked from the construction site during the spring. Please slow down and give the street sweepers room to work.

The street sweepers can create a temporary increase in dust for the surrounding areas. Thank you for your understanding while we work to clean the streets in the coming weeks.

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

We appreciate your patience during construction.

Barrier and Expansion Joint Construction

Bridge work has continued over the winter, primarily on the south side of the Bow River where the last girder segments were poured.

On the north side of the river, painting and barrier construction continues.

Grading and Nuclear Density Testing

Grading continues to shape the ramp from eastbound Highway 8 to northbound Stoney Trail. This ramp is the first level of the three-level interchange, and travels under both Stoney Trail bridges and the flyover from northbound Stoney Trail to westbound Highway 8.

The yellow machines are portable nuclear density gauges used to measure soil compaction (density) and moisture. Using a small hole created with a drill rod, radiation is emitted into the ground and scattered back to the machine to provide a measurement of moisture content or material density (Canadian Nuclear Safety Commission).
