A major traffic artery into downtown Calgary will be shutting down for construction this weekend ahead of more than a year of planned lane restrictions.
The $12.5 million rehabilitation project on the 4th Avenue flyover underwent site preparations in March ahead of construction next week — the project is not expected to be completed until the late fall of 2025.
In order for crews to setup for the work, both lanes of the bridge will close at 9 p.m. on Friday, Apr. 5, and are expected to remain closed until Monday, Apr. 8 at 5 a.m.
Stage 1 of construction begins Monday, and one lane of the flyover will be down to a single lane for the remainder of the project.
“Throughout construction, there may be lane closures of underpass roads for overhead work,” says the City of Calgary. “These closures will be temporary and during off-peak hours.”
Off-peak single lane closures of the bridge start on Tuesday, until the full closure on Friday evening.
The city says both lanes of the flyover will be open for the duration of the Calgary Stampede.
“We have coordinated the project schedule to minimize impacts to Calgarians and visitors as much as possible,” the city says.
According to the city, the project will rebuild the existing concrete barriers, add lighting, and replace concrete paving and expansion joints on the bridge.
“Construction activities are dependent on several factors,” the city says, adding the timeline may could be adjusted due to weather, complexity, supply chain, or other unexpected circumstances.
The work will aim to extend the life of the bridge by approximately 35 years.
