Cambridge — Eastbound traffic on Highway 401 at Highway 8 was halted during evening rush hour after a three-vehicle collision that left one vehicle overturned and two people requiring hospital transport, Ontario Provincial Police said.
Collision shuts all eastbound lanes
Ontario Provincial Police Sgt. Kerry Schmidt said the crash involved three vehicles, including a dump truck that rolled over, and forced the closure of all eastbound lanes along the stretch of Highway 401 that passes through Cambridge. In a video posted to X, Schmidt said emergency crews were on scene and that cleanup could take hours.
Police confirmed that two people were taken to hospital, one with minor injuries and another with serious injuries. The OPP urged motorists to avoid the area while crews work to clear the scene and investigate the collision.
Impact on commuters and local roads
Rush-hour traffic in the Kitchener–Waterloo region was disrupted as drivers diverted from the eastbound 401 to alternate routes. While authorities did not release a list of recommended detours, motorists travelling through Cambridge were warned to expect significant delays and to plan for additional travel time.
- Lanes closed: All eastbound lanes of Highway 401 at Highway 8.
- Vehicles involved: Three, including a dump truck that overturned.
- Injuries: Two people taken to hospital; one serious, one minor.
- Cleanup time: OPP indicated it could take hours.
Drivers in Cambridge depend on the 401 as a primary commuter route linking the city to Kitchener, Waterloo and points east and west. Closures of this magnitude during peak travel times ripple through local streets and can affect public transit schedules and commercial traffic that serves industrial and business areas in and around Cambridge.
Emergency response and investigation
Emergency responders were on site to stabilise vehicles, treat injured occupants and begin the cleanup. Sgt. Schmidt said significant cleanup will be required because of the overturned dump truck, which typically leads to spilled loads or fluids that must be cleared before lanes can be reopened safely.
"Three vehicles involved, a dump truck rolled over ... we will have significant clean up to attend to," Sgt. Kerry Schmidt said in a video posted to X.
Police did not provide further details on the cause of the collision, the identities of those involved, or the nature of the injuries beyond the classification of one as serious and one as minor. Investigators often remain on scene while they examine vehicle positions, roadway markings and any debris to determine sequence and contributing factors.
What drivers should know
Motorists were advised to avoid the area and consider alternate routes until authorities reopen the eastbound lanes. Commuters using the 401 through Cambridge should monitor local traffic reports and official OPP communications for updates on lane reopenings and any recommended detours.
| Detail | Known information |
|---|---|
| Number of vehicles | 3 |
| Vehicle type noted | Dump truck (rolled over) |
| People taken to hospital | 2 (one serious, one minor) |
| Lane status | All eastbound lanes closed |
As emergency crews complete their work and investigators assemble their findings, Cambridge residents and commuters should expect continued updates from the OPP and local traffic authorities. The closure underscores how a single collision on a major provincial artery can swiftly affect the daily flow of people and goods across the region.
