Watermain renewal projects on 6 Avenue S and 9 Avenue N

​The City will be undertaking two major watermain renewal projects this year which will impact traffic flow on 6 Avenue South and 9 Avenue North. 

The 6 Avenue South project will begin on April 15 and is expected to be completed by June 12, weather permitting. Sixth Avenue South will be partially closed with traffic restricted to the north half of the road. South access to 6 Avenue South will not be available at 5th, 6th, and 7th Streets.

Given the importance of 6 Avenue South as an arterial roadway, it was decided to replace the pipe from 5 Street to beyond the 7 Street intersection to reduce the risk of future water main failures and unscheduled repairs in this area.

Some residents and businesses in the area will see parking restrictions and may need to be hooked up to a temporary water supply. Those that are impacted will have already received additional correspondence.

The 9 Avenue North portion of this project will begin in early July and be completed by the middle of August to reduce the impact on nearby Wilson Middle School. Ninth Avenue North will be fully closed at the worksite location near 20 Street North for some phases of the project.

The City of Lethbridge has been replacing cast iron water mains for over forty years. Cast iron pipes, as of 2021, represent 10 per cent of the total water mains in the City of Lethbridge and nearly 100 per cent of the water main breaks.

Motorists are reminded to expect delays in the area, to drive with caution, and to follow all posted signage.
