Project Update – November 16, 2020

What’s Happening in Traffic This Week

Crestmont Boulevard S.W.

Single lane alternating traffic will be in effect along Crestmont Boulevard S.W. for the next several weeks for stormline installation and work on the slope stability wall.

We have made some adjustments to improve traffic in the winter conditions, including extending the length of the green light on the traffic signal to allow more time to get up and down the hill. Regular winter maintenance of plowing and sanding will continue. Old Banff Coach Road S.W. is an alternative route during this time. 

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

We appreciate your patience during construction.

Freshly Painted Lines

Road markings were repainted throughout the North project the week before last, just in time for another autumn snow covering! 

Forming Bridge Decks Over the Longest Girders on the Project

What is a Pier Plinth?

A pier plinth is a platform on top of a pier cap that forms a ‘seat’ to place bridge girders upon. The pier plinth helps transfer and distribute the heavy load of the bridge deck onto the piers and is a simple, yet vital part of a strong bridge structure.

Danger Reminder

Please remember to stay out of the construction zone. Soon there will be several lanes of traffic in this area and while a north-south crossing will be provided in the vicinity of the Bow Trail S.W. interchange, residents should find alternative walking paths as the informal pathways that existed before are within the construction zone and now closed

Springbank Ravine Earthworks

Parts of the Springbank ravine are being filled with soil able to support the immense weight of the future roadway structures.

Rebar: Concrete’s Hidden Strength

Rebar, short for reinforcing bar, is an important part of a strong concrete bridge structure. Concrete is extremely resilient on its own and can tolerate huge compression forces that result from the weight of vehicles. However, bridges must also be able to withstand tensile forces (fancy way of saying tension), which act to pull apart or add tension. 

Built into the concrete and often unseen, rebar strengthens concrete to resist the tension caused by thousands of vehicles passing over the bridge daily.
