What’s Happening in Traffic This Week
Eastbound Trans-Canada Highway Reduced to One Lane
The right lane on eastbound Trans-Canada Highway, east of the Stoney Trail interchange, will be closed until the morning of Wednesday, July 21 to install a catch basin. Delays are expected.
JULY 21: Traffic Shift for Valley Ridge Boulevard N.W. / Crestmont Boulevard S.W. to Eastbound Trans-Canada Highway and Northbound Stoney Trail
The access from Valley Ridge Boulevard N.W. / Crestmont Boulevard S.W. to eastbound Trans-Canada Highway and northbound Stoney Trail will be shifted to a new detour on the re-aligned West Valley Road S.W. this week. Access to businesses along West Valley Road S.W. – Calgary Climbing Centre, Calgary West Dance Academy and New Victory Church – will also be shifted to the south side using the new road alignment.
The traffic shift is currently scheduled for the early morning of Wednesday, July 21, weather permitting.
101 Street S.W. South of Heritage Woods Drive S.W.
Between 8 a.m. and 5 p.m. each day from Wednesday, July 21 until Tuesday, July 27, a portion of 101 Street S.W. south of Heritage Woods Drive S.W. will operate as a single lane of alternating traffic. ENMAX will be doing overhead and underground utility work in the area.
Trans-Canada Highway Reduced to One Lane Nightly
Each night from 10 p.m. to 5 a.m., Saturday, July 25 to Thursday, July 29, the Trans-Canada Highway will be reduced to one lane in each direction at the Stoney Trail interchange. These lane closures are required to install overhang brackets on one of the new bridges.
UPCOMING: Crestmont Boulevard S.W. Single Lane Alternating Traffic
Roadwork for the new intersection at 109 Street S.W. and the re-aligned Crestmont Boulevard S.W. is approaching completion. In preparation for shifting traffic to the new Crestmont Boulevard S.W. alignment, a short section of pavement is required to connect the new road with the existing road.
For approximately one month, Crestmont Boulevard S.W. will operate as a single lane with alternating traffic using temporary signals to complete this work. This lane closure is anticipated to begin in early August. Additional details will be provided as they become available.
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.
Valley Ridge Boulevard N.W. Interchange
The girders have arrived on site for installation on the third and final Trans-Canada Highway bridge over Valley Ridge Boulevard N.W.
109 Street / Crestmont Boulevard / 1 Avenue S.W. Intersection
Crestmont Boulevard S.W.
Asphalt pavement is an engineered structure that absorbs and distributes force. When the force from vehicles isn’t distributed you end up with a rutted surface. The asphalt is applied in several ‘lifts’ or layers, but if the layers aren’t bonded together the pavement structure is weakened and the layers can shift independently over time. This ‘slippage’ between layers results in potholes, ruts and cracks, and requires frequent maintenance.
A prime coat is applied to the subgrade (gravel) to prepare the surface for paving by filling in voids and improving bonding with the asphalt. A tack coat is an adhesive material sprayed between layers of pavement to bind them together and prolong the lifespan of the road.
Unless you live on the ridge, you might be surprised at how much progress has been made on Stoney Trail between the Trans-Canada Highway and Old Banff Coach Road S.W.
Trans-Canada Highway Improvements
Grading improvements along the Trans-Canada Highway, west of Valley Ridge Boulevard N.W., have been ongoing since traffic was shifted to the detour in April. Changes to the road elevation will reduce the steep grades, which will improve visibility and winter driving conditions.
Site inspections will be happening in a few areas near the edge of the Transportation Utility Corridor this week in preparation for utility work and stockpiling.
