Coquihalla Highway Summer Travel Alert: Major Construction Delays And Peak Volume Hit Highway 5
Travel times along British Columbia’s vital Coquihalla Highway (Highway 5) are experiencing significant spikes this weekend as peak summer travel traffic collides with planned infrastructure maintenance. Ministry officials urge motorists to prepare for unexpected delays, carry essential emergency supplies, and check real-time road conditions before departing.
| Travel Metric | Status / Advisory (As of July 25, 2026) |
|---|---|
| Route Designation | Highway 5 (Coquihalla) |
| Current Conditions | Dry, high summer temperatures, localized smoke risk |
| Primary Bottlenecks | Active construction zones near Larson Hill and the Summit |
| Average Delay Times | 20 to 45 minutes during peak daytime hours |
| Recommended Action | Travel during off-peak hours; carry ample drinking water |
Context & Background
The Coquihalla Highway, the primary artery connecting the Lower Mainland with the British Columbia Interior, is currently handling its highest traffic volumes of the year. The late-July rush brings a mix of recreational RVs, transport trucks, and passenger vehicles onto the mountain pass, testing the corridor's capacity.
Following the extensive rebuilding efforts of recent years, current provincial efforts have shifted toward long-term corridor resiliency, bridge rehabilitation, and pavement resurfacing. These seasonal preservation projects are critical for maintaining the highway's integrity through harsh winter seasons, but they necessitate temporary lane closures and reduced speed limits.
Active work zones are strategically positioned between Hope and Merritt. Road crews are working adjacent to active lanes, prompting strictly enforced speed reductions to protect on-site personnel.
Impact & Utility
The combination of extreme summer heat and heavy congestion presents unique challenges for drivers traversing the high-elevation mountain passes.
- Thermal Strain on Vehicles: The sustained, steep climbs—such as the ascent to the Great Bear Snowshed—combined with temperatures exceeding 30°C, significantly increase the risk of engine overheating and vehicle breakdowns.
- Work Zone Bottlenecks: Lane merges in active construction zones are creating sudden backups. Drivers must remain alert to changing speed limits and merging traffic patterns.
- Wildfire and Environmental Monitoring: Late July marks the height of the summer wildfire season. While the highway remains fully open, localized haze or sudden smoke drift can rapidly reduce visibility.
To ensure a safe and efficient trip, travelers should implement the following precautions:
- Inspect Your Vehicle: Prior to departure, check coolant levels, engine oil, tire pressure, and braking systems.
- Pack Emergency Supplies: Ensure your vehicle is stocked with plenty of drinking water, non-perishable snacks, first-aid kits, and mobile device chargers.
- Time Your Departure: To bypass the heaviest congestion, plan to travel during early morning or late evening hours when ambient temperatures and traffic volumes are lower.

What's Next
High-volume weekend travel is expected to persist through the upcoming August long weekend. The Ministry of Transportation and Infrastructure plans to pause non-essential maintenance operations during major holiday weekends to maximize lane capacity, though active construction zones with reduced speed limits will remain in place.
Contractors are scheduled to continue resurfacing and bridge rehabilitation projects through mid-autumn. Motorists are highly encouraged to monitor real-time updates via DriveBC and adjust their travel plans accordingly to minimize delays.
