Edmonton’s downtown is booming, thanks in great part to catalyst projects such as the Rogers Place and the Quarters Downtown. With the increasing density that comes with new condominium towers, office towers and the Edmonton Arena District also comes the need to upgrade Edmontons drainage system.

Project details

Stormwater and sanitary sewer upgrades in the area of Central McDougall/Queen Mary Park began in January 2015. The upgrades will address aging infrastructure but will also provide an opportunity to increase the capacity of the sewer system to manage the additional load resulting from the downtown growth.

Much of this work takes place deep underground so the only real disruption will be at the site of each opening to the tunnel below.

Phase 2

In mid-May 2015, phase 2 started for this vital downtown intensification drainage project. For approximately 2 years, the east side lanes on 105 Street between 104 and 105 Avenues will be completely closed to northbound traffic.

The west side lanes on 105 Street will remain open but will only accommodate southbound traffic. Therefore no northbound travel will be available on 105 Street between 104 and 105 Avenues. Any traffic needing to go north should consider taking 109 Street.


Phase 1

Drilling for the first shaft began in mid January 2015 at 111 Avenue and 107 Street. As a result, a small section of 107 Street at 111 Avenue has been closed to traffic. Drivers can access 111 Avenue from 108 Street or via Kingsway from 106 Street.

The work on this project will extend over 4 years and run south along 107 Street to 105 Avenue. Then it will shift east 2 blocks to 105 Street, and the work will continue south along 105 Street to 100 Avenue. 

Although some impact on local traffic is inevitable, effort will be made to minimize traffic disruptions. Noise will be minimal because the work takes place deep underground.
