Heavy fog forced part of an expressway in southwest China's Sichuan province to close for about 10 hours on Thursday morning.

The dense fog began from the early morning hours and covered the Chengnan expressway that links Chengdu and Nanchong in the province until ten o'clock in the morning. During the period, visibility along the highway was very poor and in some parts nothing is visible beyond 20 meters.

Reports say traffic gradually turned back to normal after 10:00 am when the fog lifted.
