​Project timeline

Construction began in March 2023 with completion anticipated by Summer 2025.

Causes of possible schedule delays

While we always do our best to plan construction and abide by construction timelines communicated to the public, unexpected events can potentially occur which may delay the schedule. Some of these factors are:

Ground Conditions and Boulders

Geotechnical investigations have been completed along the alignment and we anticipate that the ground conditions are favourable for tunneling. However, there is a risk the TBM could encounter harder soil, b​​oulders or soupy sand, which could slow down progress​.​

Extreme Weather

Extreme weather, including severe cold, heavy rains, high winds and lightning make working unsafe. During these conditions, the site will be shut down.

Relocation of Existing Utilities

The start date of the project is dependent on relocation of the utilities, including​​ a water main relocation at Worksite #5. There may be some disruption to local services; however, more information will be provided before the work starts.
