Project Update - June 21, 2021 - West Calgary Ring Road

What’s Happening in Traffic This Week

UPDATE: Trans-Canada Highway Reduced to One Lane Overnight

Until June 24, each night between 10 p.m. and 5 a.m., the Trans-Canada Highway will be reduced to a single lane in each direction at the Stoney Trail interchange for bridge work. Delays are expected.

Trans-Canada Highway Reduced to One Lane Overnight

On June 25, from 9 p.m. to 8 a.m., there will be inside lane closures on both eastbound and westbound Trans-Canada Highway. This is required for a bridge deck pour.

Shoulder Closure on Eastbound Trans-Canada Highway

Until June 25, a small section of the shoulder on eastbound Trans-Canada Highway, just east of the Stoney Trail interchange, will be closed to allow for utility work next to the road.

Construction Crossing on Township Road 242

A crossing point has been set up on Township Road 242, between Lower Springbank Road S.W. and 101 Street S.W., for hauling earthworks. The crossing will be controlled by flaggers and remain in use until mid-July 2021.

Frequent, short traffic stops can be expected. Traffic will be monitored to limit delays.

Lower Springbank Road S.W. Reduced to One Lane

Every weekday from 8 a.m. to 5 p.m., June 21 to July 9, Lower Springbank Road S.W., south of Township Road 242, will operate as a single lane of alternating traffic. Flaggers will direct traffic. Some delays should be expected.

This lane closure is to accommodate ENMAX decommissioning overhead powerlines.

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.

June 14, 2021: The wall has been backfilled to the top of the pile caissons (the steel casing around the piles)

Wetland Removal Near Highway 8

In the coming weeks, two existing wetlands near Highway 8 will be removed to facilitate ring road construction. The wetlands are in the immediate vicinity of the highway and cannot be avoided. Highway infrastructure requires strong soil foundations and cannot be constructed on top of the marshy earth of wetlands. The wetland areas will be excavated and filled with soils and gravels suitable for supporting the highway infrastructure.

Old Banff Coach Road S.W. Interchange

Centre Pier Cap

The pier cap is made of reinforced steel bars (rebar) and concrete. It helps to transfer the horizontal load from the bridge deck to the vertical piers and bridge foundation.
