Coquihalla Highway (Highway 5) Closed: Emergency Shutdown Between Hope And Merritt Due To Major Incident

The British Columbia Ministry of Transportation and Infrastructure (MOTI) has issued an emergency closure of the Coquihalla Highway (Highway 5) in both directions as of the morning of July 24, 2026. A serious multi-vehicle collision near the Great Bear Snowshed, combined with high-velocity winds and elevated wildfire risks in the surrounding canyon, has forced the total suspension of travel between Hope and Merritt. Emergency crews, including BC Highway Patrol and local fire services, are currently on-site, and there is no immediate estimated time for reopening.

Immediate Incident Overview and Emergency Response

The closure was triggered at approximately 8:15 AM on July 24, 2026, following a major incident involving two commercial semi-trailers and multiple passenger vehicles. The collision occurred in the northbound lanes, but the debris field and the requirement for a Medevac landing zone necessitated a full closure of all lanes. BC Emergency Health Services have confirmed that multiple units are staged near the Zopkios rest area to coordinate triage.

In addition to the collision, the Ministry has cited "extreme environmental volatility" as a secondary reason for the extended closure. The July 2026 heatwave has left the vegetation along the Highway 5 corridor tinder-dry. First responders are currently managing a small brush fire ignited by the collision, and the BC Wildfire Service has been deployed to ensure the blaze does not scale the steep embankments of the Coquihalla Pass.

Detour Routes and Travel Advisories

Motorists traveling between the Lower Mainland and the Interior are urged to delay their trips if possible. For those already in transit, two primary detours are available, though both are experiencing significant congestion due to the diverted volume.

• Highway 1 (Fraser Canyon): This route remains open for light passenger vehicles. However, commuters should expect heavy traffic through the tunnels and narrow sections near Yale and Spuzzum.
• Highway 3 (Crowsnest Highway): Recommended for commercial vehicles and those heading toward the Kootenays. Be advised that the Allison Pass section is seeing a 40% increase in traffic volume today, leading to significant slowdowns.

DriveBC has warned that secondary mountain passes are not equipped to handle the sudden influx of heavy transport trucks, and drivers are reminded to maintain a safe following distance in the high-temperature conditions of July 2026.

Environmental Factors: Heatwave and Wildfire Precautions

The timing of this closure is particularly challenging given the current Stage 4 drought conditions affecting the Southern Interior. With temperatures peaking near 38°C today, vehicle cooling systems are under immense stress. The Ministry of Transportation has positioned water trucks at the Hope and Merritt checkpoints to assist stranded motorists who were caught behind the initial incident line.

Safety officials are emphasizing a "zero-tolerance" policy for idling in dry grass areas along the detours. The risk of a secondary fire starting from an exhaust system is categorized as "Extreme" for the weekend of July 24-26, 2026.

Impact on Commercial Supply Chains

The Coquihalla is Canada’s primary commercial artery connecting the Port of Vancouver to the rest of the country. Today’s closure is expected to delay hundreds of shipments. Logistics firms have been advised to reroute via Highway 3, though the steep grades of the "Hope-Princeton" segment will increase fuel consumption and transit times for heavy-haulers.

Supply chain analysts suggest that if the closure extends beyond 24 hours, there may be minor disruptions in the delivery of perishable goods to the Okanagan and Thompson-Nicola regions. However, infrastructure upgrades completed in late 2025 have made the alternate routes more resilient than in previous years.

Looking Ahead: Estimated Reopening and Monitoring

The BC Highway Patrol is conducting a full forensic reconstruction of the accident site, which is standard procedure for incidents of this magnitude. This process, combined with the removal of charred wreckage and the assessment of the road surface for heat damage, suggests the highway will remain closed through at least the evening of July 24, 2026.

Motorists are encouraged to monitor DriveBC for real-time updates and to check the status of the Okanagan Connector if they are attempting to reach Kelowna. A status update from the Ministry is expected at 4:00 PM local time. For now, the priority remains the safety of the recovery crews and the containment of the roadside fire.
