The rainstorm-triggered landslide, which happened at around 11:00 a.m. beside the Wulingshan Tunnel on No. 319 National Highway, resulted in an accumulation of more than 10,000 cubic meters of earth and stone and cut off traffic from Qianjiang district to Pengshui county in Chongqing, said Zhou Xinguo, deputy director of the district's transportation commission.
