What’s Happening in Traffic This Week
Overnight Work at Stoney Trail / Trans-Canada Highway Interchange
Each night from Monday, July 5 to Saturday, July 10, crews will be working from 7 p.m. to 7 a.m. to grout post-tensioning cable ducts on several bridges at the Stoney Trail / Trans-Canada Highway interchange. The high daytime temperatures exceed the specified temperatures for the grout.
The work is happening on the southeast side of the interchange away from homes and is not expected to impact adjacent residents. Lighting will be used as required and directed away from residences.
Crestmont Boulevard S.W. Single Lane Alternating Traffic
Single lane alternating traffic will continue along Crestmont Boulevard S.W. for utility work until July 6.
REMINDER: Lower Springbank Road S.W. Single Lane of Alternating Traffic
ENMAX will be working along Lower Springbank Road S.W. to decommission overhead power lines until July 9. A single lane of alternating traffic will be in place adjacent to the areas where they are working.
We appreciate your patience during construction.
1 Avenue / 101 Street S.W. Roundabout
When a vehicle turns around a corner, the rear wheels follow a shorter path than the front wheels – this is referred to as off-tracking. Off-tracking is more pronounced in larger vehicles, so roundabouts sometimes include a truck apron that provides room for larger vehicles to safely maneuver the turn without hitting fixed objects or other vehicles.
Deck Pour on the Largest Bridge
The southbound Stoney Trail mainline bridge over the Trans-Canada Highway is the largest on the North project. It has 18 girders spanning 96 metres, which translates to about 1,000 cubic metres or one million litres of concrete for the bridge deck. The deck was poured in two stages: the north and south ends and then the middle.
When concrete is poured in stages, the first pour begins to cure before the second pour, which creates a cold joint. A cold joint is where the two concrete pours meet. A bulkhead is a naval term that means partition and is also used to describe the form used to create the cold joint.
New Ramp Opening Soon
The ramp from southbound Stoney Trail to eastbound Trans-Canada Highway has been paved and traffic is expected to be shifted in the near future. Once traffic has been shifted off the existing ramp, work can begin on the northbound Stoney Trail mainline bridge.
Mainline Stoney Trail
After 200+ controlled blasts spanning more than a year, road construction south of the Trans-Canada Highway is making visible progress.
Building Up the Trans-Canada Highway
A lot of work (and earth!) has gone into raising the elevation of the Trans-Canada Highway just west of Valley Ridge Boulevard N.W.
Old Banff Coach Road S.W. Interchange
With the centre piers largely complete, work is focused on the bridge abutments.
17 Avenue S.W. Interchange
Don’t blink or you’ll miss it! Just a few weeks ago the mud slab for this foundation was poured, and now the formwork and rebar have been installed, concrete poured and cured, and forms stripped away.
Grading the SWCRR Gravel Site
Approximately five million cubic metres of gravel was extracted from the area between Old Banff Coach Road S.W. and Bow Trail S.W. and used on the Southwest Calgary Ring Road (SWCRR) project.
