Calgary shifts northwest detour as Bearspaw water main work continues
Updated Nov. 12 at 13:44 Pacific. Calgary’s latest notice says the 83 Street N.W. detour will move from 34 Avenue N.W. to 33 Avenue N.W. on Nov. 12 as crews connect the new Bearspaw South Feeder Main. The city’s previous bulletin had given Nov. 11.
The city says traffic will alternate through a single lane. People walking will use a detour, and drivers will be unable to turn west onto 33 Avenue from 83 Street.
At 33 Avenue and 89 Street N.W., crews expect to start working around the clock on Saturday, Nov. 14, for about two weeks to complete the connection. Calgary and nearby communities used 475 million litres of water on Wednesday, below the 500-million-litre daily target. See the city’s water restrictions and project page for current guidance.
