Project Update – March 22, 2021
What’s Happening in Traffic This Week
Overnight Detour: Eastbound Trans-Canada Highway to Northbound Stoney Trail
Tonight is the last night for this ramp closure. Between 10 p.m. and 5 a.m., traffic coming from the east wanting to go north on Stoney Trail will be detoured to the Bowfort Road N.W. interchange.

Overnight detour: Southbound Stoney Trail to Eastbound Trans-Canada Highway
From 10 p.m. to 5 a.m. each night, March 22 to 25, the ramp from southbound Stoney Trail to eastbound Trans-Canada Highway will be closed for bridge work. Traffic will be detoured to the Valley Ridge Boulevard N.W. interchange.
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.
Trans-Canada Highway Detour West of Valley Ridge
Last week, the eastbound Trans-Canada Highway lanes were shifted onto the detour road east of Old Banff Coach Road. In the coming weeks, the westbound lanes will be shifted to the detour and work on the planned improvements will begin.
Please expect delays and drive cautiously through the area.

The piles have been driven to the grade of the old road (Trans-Canada Highway) 
A jackhammer breaks up asphalt and concrete from the old road 
Excavation between the piles to remove the debris and earth 
With the old road cleared, piling resumes 
The future Valley Ridge Boulevard N.W. will travel underneath the new bridge in the background (visible in the background) 
Looking north under the new bridge, the Valley Ridge Boulevard N.W. roundabout can be seen in the background
Stoney Trail / Trans-Canada Highway Interchange
This heavy-haul semi-truck is using two separate multi-axel trailers (seen at the front and back) designed for long, heavy loads such as bridge girders

Old Banff Coach Road S.W. Bridge Foundation
A mud slab is a thin layer of concrete that provides a level, dry area to work from. It is not a structural component of the bridge’s foundation, but it does serve as a platform for the wooden forms for the centre pier footing, which is a structural element.
Concrete pouring begins! 
Propane heaters maintain the temperature required for the concrete mud slab to cure under the tarps 
A crane places wooden forms for the centre footing 
Standing on the west abutment, the crane placing the formwork for the centre pier footing is visible
Earthworks at Bow Trail S.W.
Excavation is underway at Bow Trail S.W. With no existing infrastructure in this area, there is a considerable amount of earth to move.

Tree and Brush Removal within the Highway Right-of-Way
As design has progressed for the last several months, the project footprint has been refined. Some trees and brush need to be removed to accommodate utility installations, backslopes in the areas where the road is lowered and semi-permanent stockpiles of fill material.
The removals are expected to begin this week and be completed in April 2021. For more information visit westringroad.ca.
