Coquihalla Highway Travel Advisory: Summer 2026 Construction Delays, Wildfire Risks, And Critical Transit Updates
On July 24, 2026, the BC Ministry of Transportation and Infrastructure issued a comprehensive travel advisory for the Coquihalla Highway (Highway 5). Officials warn of significant peak-season congestion, active construction zones, and elevated wildfire risks between Hope and Merritt as thousands of motorists head into the Okanagan for the weekend. Drivers are urged to prepare for extended travel times, localized lane closures, and strict speed enforcement throughout the mountain corridor.
| Highway Segment | Active Condition / Construction | Estimated Delay | Speed Limit Status |
|---|---|---|---|
| Hope to Great Bear Snowshed | Bridge maintenance & seismic reinforcement | 15–20 minutes | Reduced to 80 km/h |
| Coquihalla Summit Area | High-volume tourist traffic & paving crews | Minor delays | Variable speed limits active |
| Summit to Merritt | Median barrier installation & resurfacing | 20–30 minutes | Reduced to 90 km/h in work zones |
| Merritt to Kamloops | Routine shoulder maintenance | Under 10 minutes | Standard speed limits apply |
Context & Background
The Coquihalla Highway serves as the primary high-speed economic and transit artery connecting British Columbia’s Lower Mainland to the Interior. Following the complete restoration of the corridor after historic climate events in previous years, the focus for the summer of 2026 has shifted entirely to preventative maintenance, seismic upgrades, and climate-resilient engineering. These summer 2026 maintenance schedules are specifically designed to reinforce bridges and stabilize steep slopes against future extreme weather anomalies.
With temperatures climbing across the province this July, the risk of wildfires near the corridor has reached "high" to "extreme" levels. Emergency crews are currently stationed along key points of Highway 5, and regional officials have put strict bans on any activities that could spark roadside fires. Motorists are reminded that parking vehicles in tall, dry grass on the highway shoulders is strictly prohibited.
Impact & Utility for Drivers
To navigate these summer challenges safely, travelers must utilize real-time resources and plan their journeys during off-peak hours. The DriveBC portal remains the essential resource for live updates, offering access to high-definition highway webcams and active incident reports.

- EV Charging Alert: Fast-charging stations in Hope and Merritt are experiencing high seasonal demand; electric vehicle drivers should expect wait times during peak weekend transit hours.
- Commercial Trucking Guidelines: Fleet operators are advised to inspect brake systems frequently, especially when descending steep grades like the Great Bear Snowshed or Larson Hill under high ambient summer temperatures.
- Safety Compliance: Police patrols have been ramped up along the entire route, with zero tolerance for tailgating and speeding through designated construction zones.

What's Next for Highway 5
Looking ahead, traffic volumes on the Coquihalla Highway are expected to peak further during the upcoming August Long Weekend. To help ease the flow of holiday traffic, the Ministry of Transportation and Infrastructure plans to temporarily pause non-essential daytime construction from August 1 to August 3, 2026. However, regular night-time maintenance will continue, and drivers are encouraged to keep emergency water, food, and fully charged mobile devices in their vehicles at all times.
