Project Update – November 1, 2021

What’s Happening in Traffic This Week

Eastbound Trans-Canada Highway Reduced to One Lane

From 8 a.m. to 3 p.m. each day until November 5, 2021, the right lane on eastbound Trans-Canada Highway will be closed east of Old Banff Coach Road.

Please expect delays.

Single Lane of Alternating Traffic on 17 Avenue S.W. (Township Road 242)

On Tuesday, November 2, and Wednesday, November 3, 17 Avenue S.W. (Township Road 242) will operate as a single lane of alternating traffic from 8 a.m. until 4 p.m. each day for streetlight installation.

Stoney Trail Reduced to One Lane

On the nights of November 4 and 5, 2021, from 7 p.m. until 6 a.m., Stoney Trail will be reduced to one lane in both directions over the Bow River for bridge maintenance.

Please expect delays.

Various Lane Closures on 17 Avenue S.W. – Slopeview Drive to Cortina Drive S.W.

For at least six weeks (mid-December 2021), ENMAX will be working along 17 Avenue S.W. between Slopeview Drive and Cortina Drive S.W., and along a short section of 93 Street S.W. just north of 17 Avenue S.W. The work involves removing the overhead power line on the north side of 17 Avenue S.W. and burying it on the south side.

Various lane closures will be required to complete this work.

The underground work is expected to cross Cortina Drive S.W. this week, which will involve closing the southbound lanes and then the northbound lanes as the equipment is installed under the road. One lane of traffic in each direction will remain open.

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.

Highway 8 Interchange Construction

Pile Driving for Bridges

Pile driving for the future Highway 8 and Stoney Trail interchange is anticipated to start this week and continue until January 2022. 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 may feel some vibrations while piling is ongoing.

Temporary Shoring Wall

Piles have been installed for a temporary shoring wall just north of the existing lanes. Shoring walls are temporary structures used in several ways during construction. In this case, the shoring wall will retain soil during excavation for the bridge.

Trenching for Storm Line Installation

Earthwork South of Highway 8

Earthwork is underway south of Highway 8 to prepare for construction of the ultimate highway alignment south of the existing lanes.

Tree Trimming

As part of the power line relocations happening along 17 Avenue S.W. east of 101 Street S.W., some trees and vegetation growing too close to electrical equipment will be trimmed or possibly removed to maintain safe minimum clearances from power lines. Please see the construction notice for more information.
