Main St. water main & sanitary/storm sewer upgrades

Main Street is open for through traffic.

Construction will resume in spring 2020.

The City of Airdrie Capital Projects department will be installing new water mains, sanitary sewer and storm sewer pipe along Main Street. During this project sections of Main Street will be completely closed. We encourage motorists to use 8 St. and Edmonton Trail as alternative north-south routes during construction.

The full closure of Main Street versus a partial closure allows the project to be:
• Less expensive
• Completed sooner

The water and sanitary sewer pipe needs to be replaced as the current system is reaching the end of its life cycle.

This project will prepare us for future growth and help ensure that our
infrastructure does not fail at inopportune times. Detour information will be
posted here for each phase of construction.

Timeline update

The Main St. water main & sanitary/storm sewer upgrades from Veterans BV. to Elk Hill were scheduled to be completed by Oct. 31, 2019; however, underground conditions and uncooperative weather has put the contractor behind schedule. Due to this delay, the City has made adjustments to our construction timelines. 

We understand that this construction has had an impact on residents and businesses. We thank you for your understanding and patience and we will continue to provide updates as we have them.
