A pair of significant road closures that are planned to last until the end of 2023, will affect commuter and visitor access to Calgary’s downtown, the north end of Stampede Park, the Saddledome, and the east end of the Beltline.
Starting on Aug. 8, three middle lanes of traffic on 5 Avenue SW between 2 Street SW and 3 Street SW will be closed for deep underground excavation work for the Green Line.
That work is expected to last until Sept. 25, and is required to move utility infrastructure from the future underground Green Line tunnel.
“Crews will be working extended shifts on weekends when traffic downtown is minimal to complete this work as quickly as possible,” said the City of Calgary.
“Although there will be no activity on site on Tuesdays, the lanes must remain closed due to the large open excavation site, which cannot be temporarily covered.”
Phase two of the project will close 3 Street SW between 5 Avenue and 6 Avenue SW between Sept. 22 and Oct. 22.
Construction on phase three will close two lanes of traffic on 6 Avenue SW starting on Oct. 23, and lasting until early January 2024.
4 Street SE underpass closed until late 2023
Green Line construction is also starting back up, after a summer hiatus that began with the Calgary Stampede.
Starting on Aug. 8, the 11 Avenue SE and 4 Street SE (Olympic Way) intersection will be closed, which the City of Calgary said will also close the 4 Street SE underpass to vehicles.
The road closure is expected to last until the end of the year.
Roads affected will be between 9 Avenue SE to 12 Avenue SE on 4 Street SE, and 11 Avenue SE between 4 Street SE and 5 Street SE.
Pedestrian and cyclist access via the underpass is being maintained.
The City of Calgary said they will be maintaining local residential and commercial building access on 11 Avenue SE, west of the construction.
Access to Ramsay from the Beltline will be via 6 Street SE and 12 Avenue SE, via the detour signage.
