Work linked to the Giant Mine Remediation Project that has prompted temporary delays on the Ingraham Trail near Yellowknife is expected to finish the rock-blasting phase by the end of the month, but provincial and project officials warn motorists that construction on two intersections will continue through August.
What drivers are seeing
Signs about blasting and the sight of heavy rubber "blast mats" — shredded tires lashed together with rebar and placed over explosives to dampen sound and contain dust and debris — have been visible to those travelling past the Giant Mine Scenic Viewpoint pullout. The blasting is part of remediation work at the defunct mine site northeast of Yellowknife.
The project’s deputy director, Candace Ross, provided a summer update in an interview with CBC News, confirming the short-term nature of the blasting activity and outlining the road improvements being put in place to support remediation traffic while limiting disruption for the travelling public.
Intersection upgrades and traffic management
The remediation team is upgrading two intersections on the Ingraham Trail. According to Ross, one of those intersections will evolve into the project’s primary site access. Planned changes include added turning lanes, a bypass lane and widened entrances to ease truck movements tied to the cleanup effort.
"We are adding some turning lanes, we will be adding a bypass lane and we are widening the entrances for truck traffic related to our remediation project," said Candace Ross.
Officials say these changes are intended to keep remediation-related vehicles from impeding normal traffic flow along the corridor as waste-management and construction vehicles move in and out of the site.
- Blasting phase: scheduled to wrap up by the end of the month.
- Road work: intersection upgrades continue through August.
- Long-term cleanup: Giant Mine remediation work is planned through 2038.
Why the work matters
The Giant Mine Remediation Project is a significant, long-running environmental effort. While the immediate highway work focuses on traffic flow and safety during construction, the broader remediation is aimed at addressing contamination and hazards left by decades of past mining activity. Project leaders have repeatedly signalled that the work will continue across multiple years, with completion currently scheduled for 2038.

|---|---|
| Rock blasting near scenic viewpoint | Completing by end of the month |
| Intersection upgrades on Ingraham Trail | Continuing through August |
| Giant Mine remediation project | Planned completion: 2038 |
Motorists have reported intermittent delays as crews conduct blasting with noise and dust mitigation measures in place. The use of rubber mats and other containment steps is standard for the controlled demolition work, designed to muffle the blasts and keep rock and dust from dispersing widely.
Officials involved in the remediation and the roadwork say they will continue to coordinate to minimise impacts to local traffic while maintaining safety for workers and the public. Residents who regularly travel the Ingraham Trail are advised to heed signage, expect occasional delays and allow extra time during peak construction periods.
The Giant Mine site remains a focal point for Yellowknife’s environmental and public-safety planning. While the highway improvements are a relatively short-term phase of activity, they reflect the larger logistical needs of a multi-decade remediation effort that will shape access and traffic patterns for the area for years to come.
