A minor mud slide reduced early morning rush hour traffic down to one lane on the Hart Highway. The mud slid onto the southbound lane about 500 metres from the John Hart Bridge. YRB & Ministry of Highways are on scene accessing the impact of the slide. The portion of the slide on the highway is about four metres in length and half a metre deep. Witness say they noticed the slide late yesterday evening. Traffic control crews are on scene directing traffic around the slide. No word yet from crews when the traffic will return to normal.
