Coquihalla Highway Travel Alert: Summer Delays, Construction Zones, And Key Routes To Watch Today
Commuters and road-trippers tackling British Columbia’s Highway 5 today, July 25, 2026, must prepare for high-volume summer traffic, localized construction slowdowns, and elevated seasonal temperature risks. The BC Ministry of Transportation and Infrastructure urges motorists to expect delays and plan extra travel time, particularly on the stretch between Hope and Merritt.
| Route Section | Current Status | Impact & Delay Estimate |
|---|---|---|
| Hope to Merritt | Open | 15–30 minute delays near active work zones |
| Merritt to Kamloops | Open | Normal flow; watch for high-volume merging |
| Larson Hill | Open | Heavy congestion during peak afternoon hours |
| Great Bear Snowshed | Open | Steep grades; high risk of vehicle overheating |
Current Corridor Conditions and Summer Congestion
The Coquihalla Highway (Highway 5) remains the primary artery connecting the Lower Mainland to the British Columbia Interior. Today, July 25, 2026, the route is experiencing its typical peak-summer surge as travelers head east for weekend getaways and vacations. The combination of heavy recreational vehicles, commercial semi-trucks, and standard passenger cars is putting significant pressure on the high-elevation mountain passes.
While the highway is fully open in both directions, several scheduled maintenance projects are currently active. Crews are utilizing the dry summer weather to complete asphalt resurfacing and bridge maintenance, particularly in the areas surrounding Box Canyon and the Larson Hill corridor. These work zones have reduced lanes and lowered speed limits, creating minor bottlenecks that peak during midday and late afternoon.
Furthermore, the BC Wildfire Service is closely monitoring the surrounding region. Although no active wildfires are currently threatening Highway 5 today, localized smoke and haze from interior fires may periodically reduce visibility. Drivers are reminded to keep their headlights on and remain vigilant for sudden changes in road-side conditions.
Impact on Travelers and Road Safety
The steep climbs of the Coquihalla present unique challenges during the late July heat. Temperatures in the mountain passes are hovering near seasonal highs, placing extra mechanical strain on vehicles. Overheating remains one of the leading causes of highway stoppages during this time of year, particularly on the grueling ascent toward the Great Bear Snowshed.
To ensure a safe and smooth journey today, motorists should implement the following precautions:
- Monitor Engine Temperatures: Turn off air conditioning temporarily if your vehicle's temperature gauge begins to climb during steep ascents.
- Adhere to Variable Speed Signs: Speed limits are dynamically adjusted through construction zones and high-congestion areas to protect road crews and drivers.
- Keep a Safe Following Distance: High-volume traffic increases the risk of rear-end collisions, especially in zones where lanes merge or narrow.
- Pack Essential Supplies: Carry extra water, non-perishable snacks, and fully charged mobile devices in case of unexpected, prolonged delays.

What's Next for Weekend Travel
Traffic volumes are projected to remain exceptionally high through the remainder of the weekend. Transportation analysts anticipate a massive westbound return rush on Sunday, July 26, as travelers head back to the Lower Mainland. Heavy congestion is expected to peak between 2:00 PM and 8:00 PM tomorrow.
Long-term infrastructure improvements are scheduled to continue throughout the remainder of 2026. These projects are designed to permanently fortify the corridor against extreme weather events and handle growing transit demands. For real-time camera feeds, active collision reports, and immediate detour alerts, drivers are strongly encouraged to check DriveBC before starting their engines.
