Dense fog in Sichuan province on 18 November caused major disruption to transport in the province, with airports and expressways forced to close, according to China Daily.

In the provincial capital Chengdu, Shuangliu International Airport was closed for most of the morning as visibility fell below 50 metres. A total of 105 flights to and from the airport were delayed and more than 10,000 passengers were stranded. Some incoming flights were forced to land at airports in the nearby cities of Chongqing and Kunming.

At least four expressways, including those connecting Chengdu and Dujiangyan and Dazhou and Chongqing, were closed in the morning.

Similar conditions in Beijing also caused transport chaos in the Chinese capital.
