Is there a traffic jam between Shanghai and Shaoxing on National Day?

During the National Day, there may be traffic jams between Shanghai and Shaoxing, because the National Day is an important festival in China, and many people choose to travel. There is a busy expressway between Shanghai and Shaoxing, so the traffic pressure is heavy, which may lead to traffic jams. I suggest you plan your trip in advance, know the real-time traffic situation before you travel, and choose the appropriate travel time. At the same time, you can also consider other modes of transportation, such as high-speed rail or flights.
