Ontario Provincial Police (OPP) have closed Plank Line in Tillsonburg following a serious crash on July 4, 2026. The closure, announced at 1:29 PM EDT, affects a stretch of the road as investigators work to determine the cause of the collision.
No Injuries Reported Yet
According to OPP spokesperson Constable Kate Otterbein, initial reports indicate that no injuries have been confirmed, though the scene remains active. Emergency crews are on site, and motorists are advised to avoid the area. Detours have been set up via local roads, but no timeline for reopening has been provided.
Investigation Ongoing
The OPP’s collision reconstruction team has been dispatched to gather evidence. The cause of the crash is under investigation, and authorities are asking anyone with dashcam footage or information to contact the Tillsonburg OPP detachment. “We urge drivers to exercise caution and follow detour signs,” Otterbein said.
Plank Line is a key route connecting Highway 3 to regional roads, and its closure is expected to cause delays during the afternoon commute. Local residents have been notified through emergency alerts.
Broader Context
The crash comes amid a busy summer travel season in Ontario, with OPP reporting increased traffic enforcement. In 2025, the province recorded over 300 fatalities on roads, prompting calls for safer driving practices. This incident adds to a series of recent collisions in the region, including a fatal crash in nearby Woodstock last month.
Updates will be provided as the investigation progresses. Motorists can check Ontario 511 for real-time road conditions.
