A large number of cars, over 1,000 at the peak, were stranded on the road near the border of Anji County, Zhejiang and Ningguo, Anhui, causing congestion stretching over 10 kilometers.

Workers are still cleaning ice and snow from the road, authorities in Zhejiang said.

Many areas of central and eastern China have been hit by ongoing snow and rain.

The Zhejiang provincial meteorological center said that rain and snow will continue until the end of this month.

The provincial capital Hangzhou has seen snow since Wednesday. Some 20 cars were badly damaged in a rear-end accident on an expressway in the city on Wednesday night.
