project area map Project Status & Update:

The project is underway and consists of 3 phases.

​Includes Sideroad 10 from Line 6 to north of Line 5, a roundabout south of Line 6, and Line 6 from approx 100 meters west of Sideroad 10 to east of Langford Blvd.   
​Includes Line 5 from Coffey Road to Sideroad 10 with a new tie-in to Line 5.
​Includes Sideroad 10 from Line 6 to Holland Street.

The project is currently in the first phase and construction activities are ongoing. All emergency services, school buses, and garbage pick-up have been contacted and informed about the project and relevant detours.

Over the course of the next few months, the contractor will be working on:

  • road crossing culverts,
  • driveway culverts,
  • regrading ditches
  • building bioswales.
  • Other misc works as required by the contract

​Drivers should expect some minor delays as the contractor will need to close lanes in order to complete the works noted above. Any full road closures will be posted well in advance on this webpage as well as on the variable message signs located around the project.​
