Current Road Conditions: Sinkhole Closure and Construction Delays

The Coquihalla Highway, stretching from Hope to Kamloops via Merritt, is currently experiencing a major disruption due to a sinkhole, alongside ongoing construction. Here’s the latest:

Northbound Closure Due to Sinkhole: As of June 5, 2025, the northbound section of Highway 5 between Hope and Merritt is closed near the Box Canyon Chain-Up area due to a sinkhole that appeared suddenly. Emergency repairs are underway, with assessments ongoing. The next update is scheduled for June 6 at 7:00 AM PDT, according to YRB Nicola and DriveBC. Travelers are advised to use alternate routes, Highway 1 (Trans-Canada) or Highway 3, which may add 45 minutes to 2 hours to travel times due to winding routes and potential delays.
Construction Work: Construction is ongoing in both directions between Exit 202 (Portia) and Exit 228 (Coquihalla Lakes Rd) until approximately June 25, 2025. The left lane is closed, and speed limits are reduced, with delays of up to 30 minutes expected during peak work hours (7:30 PM–9:00 PM PDT). Nightly construction between Exit 202 and Exit 217 (Zopkios Brake Check) may cause delays of up to 1 hour from 10:00 PM to midnight. Motorists should slow down and exercise caution in these zones.
Weather Conditions: Environment Canada’s forecast for June 6 indicates clear skies overnight, transitioning to sunny conditions with increasing cloudiness by afternoon. Winds may intensify, with a 70% chance of showers late Friday night and snow levels dropping to 1,200 meters near the Coquihalla Summit (1,244 meters). No severe weather alerts are currently in effect, but mountain weather can change rapidly, potentially impacting visibility and road safety.

Coquihalla Highway Overview: A Challenging Route

The Coquihalla Highway, often called “the Coq,” spans 186 km from Hope to Kamloops, passing through the Coquihalla Summit (1,244 m) and Surrey Lake Summit (1,444 m). Built in 1986 for Expo 86, it’s a four-to-six-lane freeway with steep inclines, particularly northbound through the Great Bear Snow Shed, 35 km north of Hope. The highway’s high elevation and mountainous terrain make it prone to sudden weather changes, especially in winter, though summer conditions can also bring challenges like fog or overheating vehicles.

Key Points:
- Hope to Merritt (115 km): Features the steep ascent to the Coquihalla Summit, passing the Great Bear Snow Shed and the former toll booth (tolls removed in 2008). This section is currently affected by the sinkhole closure.
- Merritt to Kamloops (71 km): Includes the Clapperton Creek Summit and five interchanges, ending at the Afton area of Kamloops.
- Okanagan Connector (Highway 97C): Links Merritt to West Kelowna, with a speed limit of 110 km/h and ongoing maintenance.

Safety Tips for Traveling the Coquihalla

Given the current closure and construction, here are essential tips to navigate the Coquihalla safely:

Check Road Conditions: Visit DriveBC.ca for real-time updates, webcams, and alternate route information. Follow @DriveBC on X for alerts.
Use Alternate Routes: With the northbound closure, take Highway 1 (Fraser Canyon) or Highway 3 (Hope-Princeton). Expect delays due to single-lane sections, ongoing repairs, or avalanche control on Highway 1.
Prepare for Delays: Construction between Portia and Coquihalla Lakes Rd may cause 30–60-minute delays. Plan extra travel time and avoid peak construction hours (evenings).
Vehicle Readiness: Ensure your vehicle has a full tank of gas, as the stretch between Hope and Merritt (115 km) has limited fuel stations. Carry food, water, and warm clothing in case of unexpected stops. Electric vehicle (EV) drivers should note that Britton Creek charging stations are out of service; use stations in Hope or Merritt.
Drive Defensively: Reduced speed limits are enforced in construction zones, with increased BC Highway Patrol presence. Watch for trucks merging or exiting, and be cautious of sudden weather changes like fog or showers.
Summer Considerations: While winter tires are not mandatory in June (required October 1–April 30), monitor your vehicle for overheating on steep inclines, especially in warmer weather.

Recent Incidents and Historical Context

The Coquihalla has a history of challenging conditions:

Past Closures: The highway faced significant closures due to flooding in November 2021, damaging 20 sites and seven bridges, and a multi-vehicle crash in October 2023 caused by snow and black ice.
Sinkhole Impact: The current sinkhole near Box Canyon is a rare event, reminiscent of the 2021 atmospheric river damage. Emergency repairs are prioritized, but no reopening timeline has been confirmed.
Avalanche Risk: While less relevant in June, the highway’s 135 avalanche paths make it prone to winter closures, as seen in March 2023 when 70 cm of snow fell in 48 hours.
