A nine-day traffic jam in China is now more than 100 kilometres long and could last for weeks, state media reported Monday.

Thousands of trucks en route to Beijing from Huai'an in the southeast have been backed up since Aug. 14, making the National Expressway 100 impassable, Xinhua News reported.

A spokesman for the Beijing Traffic Management Bureau reportedly told China's Global Times newspaper that the backup was due to "insufficient traffic capacity … caused by maintenance construction."

What's the longest time you've spent stuck in a traffic jam? Take our poll.

The construction is scheduled to last until Sept. 13.

Stranded drivers appear to have few options when it comes to dealing with the jam.

At least some drivers have complained that roadside vendors have increased their prices to take advantage of the traffic jam. One truck driver said he bought instant noodles from one vendor for four times the original price.

Another driver, Wang, told Xinhua he'd been stuck in the traffic jam for three days and two nights.

"We are advised to take detours, but I would rather stay here since I will travel more distance and increase my costs," Wang said.

This is not the first time the highway has faced such congestion.

A similar backup in July kept traffic to a crawl for nearly a month, Xinhua reported.
