Coquihalla Highway Closure: Urgent Advisories And Detours Issued For Highway 5

Motorists traveling between Hope and Merritt on British Columbia’s Coquihalla Highway (Highway 5) are facing significant travel disruptions on July 24, 2026, due to a sudden multi-vehicle incident combined with active summer construction. DriveBC has issued an urgent travel advisory warning of multi-hour delays, lane closures, and heavily congested detour routes. Transportation officials urge drivers to plan ahead, prepare for high summer temperatures, and consider postponing non-essential travel through the mountain pass today.

Highway Segment Current Status Cause of Delay / Closure Recommended Detour Estimated Delay Time Hope to Merritt (Northbound) Single Lane Alternating Multi-Vehicle Incident & Recovery Highway 1 or Highway 3 45–60 Minutes Merritt to Kamloops Fully Open Regular Summer Construction N/A Minor Delays Zopkios Rest Area Restricted Access Emergency Maintenance Work N/A Localized Delays Portia Bridge Section Lane Merges Scheduled Bridge Rehabilitation Highway 1 (Fraser Canyon) 15–30 Minutes

Immediate Traffic Impact and Alternate Routes

The primary bottleneck on July 24, 2026, stems from an emergency vehicle recovery operation near the Zopkios summit, which has reduced northbound traffic to a single lane. First responders and heavy-tow crews are actively working on-site, but full clearance is not expected until later this evening.

For travelers looking to bypass the Coquihalla delays, the BC Ministry of Transportation recommends utilizing Highway 1 (Fraser Canyon) or Highway 3 (Crowsnest Highway). However, both alternative routes are already experiencing increased volume and slower-than-average travel times as vehicles divert away from Highway 5. Commercial truck drivers should remain aware of weight and length restrictions active on Highway 3 before rerouting.

2026 Infrastructure Upgrades and Summer Maintenance

Beyond today's sudden incident, the Coquihalla corridor is currently undergoing its scheduled Summer 2026 Infrastructure Improvement Plan. This multi-site initiative focuses on reinforcing bridge abutments and paving segments damaged during previous extreme weather cycles.

Key ongoing projects causing routine delays this season include:

Bridge Rehabilitation: Structural reinforcing at the Portia and Juliet bridge crossings. Repaving Projects: Alternating lane closures between Box Canyon and the summit to lay climate-resilient asphalt. Slope Stabilization: Rockfall mitigation and barrier installations along steep canyon walls to prevent debris slides during the upcoming autumn rains.

These long-term projects mean that even after today's accident is cleared, commuters should anticipate localized single-lane patterns and reduced speed zones through late September 2026.

Essential Safety Tips for Mountain Commuters

With peak summer heat affecting the region, idling on mountain passes poses distinct safety hazards for both vehicles and passengers. Drivers are advised to carry plenty of drinking water, ensure their vehicle's cooling systems are fully functional, and keep fuel tanks at least half full.

Real-time highway cameras, delay estimates, and official road condition updates are accessible via the DriveBC portal. Commuters should check these resources immediately before departure to make informed routing decisions.

What's Next for Highway 5 Travelers

Emergency crews expect to restore regular multi-lane traffic flow on the Hope-to-Merritt corridor by late tonight, though residual congestion will likely impact Saturday morning travel on July 25, 2026. Long-term summer construction delays will persist throughout the weekend, making early morning or late evening travel the most efficient options for navigating Highway 5 over the coming weeks.
