Westbound Trans-Canada Highway to Northbound Stoney Trail Ramp
The ramp from westbound Trans-Canada Highway to northbound Stoney Trail will be reduced to one lane until the end of the week.
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.
We appreciate your patience during construction.
Segmental Bridge Construction
Like stationary wooden forms that are used to shape concrete for bridge abutments, curbs and retaining walls (to name a few), form travellers are pre-assembled forms used to construct segmental bridges.
Segmental bridges, like this one, are constructed using many shorter segments whereas a more traditional bridge is constructed in large segments using girders.
Segmental bridges are often used when long spans are required or when access to the site is limited.
Looking north at forms for the first segment on the south side pier – the first segment on a pier is created with traditional stationary wooden forms because the form traveler needs to attach to something
Trans-Canada Highway Improvements
Now that westbound Trans-Canada Highway traffic has been shifted to the new lanes, work on the future eastbound lanes is underway.
Looking west at road construction for Trans-Canada Highway improvements 
The road in this section will be lowered approximately eight metres below the original elevation; the detour road shown on the left is lower than the original elevation and the new lanes shown on the right are at the new elevation 
This section of road is being raised approximately seven metres

Deck Pour Preparation
The truss screed – named because of its triangular shape – is installed, signaling the bridge deck is ready for concrete.
Screeding is the process of flattening and smoothing wet concrete. The truss screed is mounted on rails on either side of the bridge deck, and a screed attachment will be suspended from the truss allowing it to move back and forth to level and finish the concrete.

Bow Trail S.W.
