Three lanes have been closed on southbound Highway 400 after a tractor-trailer rollover. The collision happened near Finch Avenue shortly after 10 a.m. Paramedics say that one person was rushed to hospital with serious injuries as a result of the rollover. CP24 Traffic Specialist Adwoa Nsiah-Yeboah says that motorists should expect significant delays in the area. “It is pretty extensive. It (the backup) does extend until before Steeles Avenue,” she said. It is not clear when the highway will reopen. Ontario Provincial Police are telling motorists to avoid the area.
