Traffic on Highway 400 has largely returned to normal after emergency crews responded to a serious incident that caused a fuel spill and temporary lane closures earlier this week.
According to an update released at 2:30 p.m. on June 30, 2026, the Saint John Fire Department has completed its emergency response and cleared the scene. While firefighters have departed, specialized cleanup crews remain at the location to remove spilled fuel, clear debris, and complete environmental remediation efforts.
Emergency responders were dispatched shortly after the incident was reported, working to secure the affected section of the highway and prevent further hazards. Firefighters coordinated with police, transportation officials, and environmental response teams to stabilize the area before traffic could safely resume.
The eastbound lanes, which had been closed during the emergency operation, have since reopened to motorists. However, officials advise drivers to expect minor delays as cleanup personnel continue working along the roadside. Motorists are encouraged to slow down, stay alert, and obey traffic control measures while crews finish their work.
Authorities have not yet disclosed the cause of the incident or confirmed whether anyone was injured. The circumstances surrounding the event remain under review as part of the ongoing investigation.
Officials praised the coordinated response by emergency services and transportation agencies, noting that their efforts helped restore traffic flow as quickly and safely as possible while minimizing risks to the public.
Drivers traveling through the area are encouraged to monitor official traffic advisories for any temporary restrictions that may remain in effect until cleanup and roadway inspections are fully completed.
Authorities also remind motorists to use extra caution when approaching emergency vehicles and highway maintenance crews, helping protect workers and other road users as final cleanup operations continue.
