The congestion was caused by a new checkpoint at the other side of the toll, which reduced the width of the road from 50 to less than 20 lanes.

Known as the 'Golden Week', the Chinese National Day celebration witnesses an explosion in tourism every year. It's one of the few opportunities for people to get time off work and enjoy a long-distance holiday.
China's National Tourism Administration estimated that more than 750 million Chinese would be on the move between October 1 and 7, which is half of the nation’s population.
The figure marks a 6.1 year-on-year increase.
