What’s Happening in Traffic This Week

Nightly Lane Closures on Trans-Canada Highway

The Trans-Canada Highway will be reduced to one lane in each direction starting at 9 p.m. each night until 6 a.m. each morning, ending the morning of Friday, March 11. These lane closures are required for bridge work at the Stoney Trail interchange.

Daily Westbound Trans-Canada Highway Lane Closure

From 7 a.m. to 5 p.m. each day until Friday, March 11, the right lane on westbound Trans-Canada Highway will be closed approaching Stoney Trail for work on the north side of the road.

Intermittent Traffic Delays on Highway 8

Starting today and continuing for approximately one week, girders for the Highway 8 / Stoney Trail interchange bridges will be delivered to the construction site via westbound Highway 8. There will be intermittent delays as the trucks turn north (right) onto the site. 

Each day, three girders are anticipated to be delivered during daylight hours.

Eastbound Lane Closure on 17 Avenue S.W.

Today and tomorrow, from 9 a.m. to 4 p.m., 17 Avenue S.W. will be reduced to a single lane of alternating traffic west of 85 Street S.W. for utility work. Flag people will direct traffic.

Utility work in this area is ongoing and intermittent delays can be expected in the coming weeks.


All work is weather dependant. Please check 511 Alberta and The City of Calgary’s traffic information map  for up-to-date information on traffic detours and speed reductions.

We appreciate your patience during construction.

South Pier Progress

Construction of the box girder segment on top of the southernmost pier is progressing. In February the concrete was poured for all the structural members of the girder except the top slab.

The diaphragm on a box girder segment is intended to keep the sub-structure square; that is, to maintain the shape of the girder.

With all the girder components poured, steel falsework is being set up to support the formwork for the top slab.

North Side Superstructure

On the north side of the river where the sub-structure is complete, work on the bridge deck (superstructure) is underway.
